readings:
-
US
Organic silicones
Silicates
Lead-containing compounds
Sulfur compound exposures over 200 ppm or exposures over 50 ppm for one minute
High concentration of VOC gas may affect CO sensor performance
The minimum concentration of a combustible gas in air that can ignite is defined as the Lower
Explosive Limit (LEL). A combustible gas reading of XXX indicates the atmosphere is above
100 % LEL, and an explosion hazard exists. Move away from hazardous area immediately.
Do not use the device to test for combustible or toxic gases in the following atmospheres as this
may result in erroneous readings:
-
Oxygen-deficient or oxygen-rich atmospheres

PID Theory and Definitions
To support the safe and effective operation of the ALTAIR 5X PID, MSA believes operators should
have a working knowledge of how the device functions, not just how to make it work. The information
presented in this section supplements the hands-on operational instruction provided in the rest of the
manual for the PID.
PID Theory
A photoionization detector (PID) uses an ultraviolet lamp to ionize the compound of interest. A current
is produced in proportion to the concentration of the VOC present, and the concentration of the
compound is shown on the device display.

Zero Gas
Zero gas is a reference gas used during calibration to zero the device. When a zero gas with no hydrocarbon content is introduced to the device, the detector will still respond with a small signal. This signal
is a result of secondary background processes. During calibration, zero gas is applied to quantify the
background ionization current.
When only measuring concentration changes relative to a reference ambient environment, fresh air
can be used as the zero gas. When background hydrocarbon vapors are present, MSA recommends
using zero gas air.
ALTAIR 5X PID
11
PID Theory and Definitions
Span Gas
Span gas is a reference gas used during calibration to determine the slope (response per unit concentration) of the calibrated response curve.
For the 0-2000 ppm PID sensor the allowable calibration gas is 100 ppm isobutylene.
See Chapter 4.10 for calibration instructions.
Response Factors
When a compound is ionized by photoionization, the ionized molecules are collected and converted to
a current. This response is a characteristic property of the specific compound which is influenced by
its molecular structure. The slope of the response curve (defined in picoamperes per ppm) is different
for different chemicals. To properly report the concentration for a given sample gas, the ALTAIR 5X
PID uses response factors. See Chapter 10, for instructions on using the pre-programmed list of
response factors.
WARNING
It is very important to have an understanding of PID basics when changing PID settings. Failure to
properly identify the VOC gas being measured and/or failures to select the correct Response Factor
alarm values (exposure, STEL, TWA) that match the desired Response Factor and/or the correct
lamp will result in erroneous readings or erroneous alarm limits that could cause death or serious
personal injury.
The response factor is defined as the ratio of the detector response for isobutylene to the detector
response for the sample gas. Response factors for a wide range of substances have been determined
experimentally. These response factors are programmed into the device. Note that the calibrated
response curve, and all programmed response factors are relative to isobutylene. Isobutylene has a
response factor of one.
The response factor is a multiplier that compensates for the difference between the response of the
sample gas and the response of isobutylene at 100ppm. Whenever the device detects the presence
of a VOC, it uses the response factor for the user-assigned target gas to convert the signal to the
correct, concentration. This is done by multiplying the equivalent isobutylene response by the response
factor for the set sample gas. The isobutylene response curve is calculated at every calibration.
If the response factor is known, a device calibrated with isobutylene can be used to calculate the actual
concentration of a target gas.
For example:
An operator is using a device that has been calibrated on isobutylene. The sample gas is set to isobutylene. While using this device to sample for hexane, the display reads 100 ppm. Since the response
factor for hexane is 4.5, the actual concentration of hexane is:
US
Actual hexane concentration = 4.5 x 100 ppm = 450 ppm.
Calculating a Response Factor
To determine a response factor for a target chemical, perform the following simple procedure:
(1)
Calibrate the ALTAIR 5X PID using isobutylene as the span gas.
(2)
On the device, set the sample gas name to isobutylene.
(3)
Apply a known concentration of the target chemical to the device and note the concentration
reported in the display.
The response factor for the target chemical relative to isobutylene:
RF target gas
=
Actual known concentration
Concentration reported by device
For example:
A device is calibrated on isobutylene, and has isobutylene defined as the sample gas. When sampling
106 ppm of benzene in air, the device reports a concentration of 200 ppm. In this example, the
response factor for benzene relative to isobutylene would be:
RF benzene
=
106 ppm known concentration benzene
200 ppm reported
ALTAIR 5X PID
=0.53
12
PID Theory and Definitions
When surveying, if benzene is selected as the sample gas in the Response Factor page, 0.53 will be
used by the device as a response factor. The device will use this response factor to automatically
correct the displayed concentration into PPM benzene.
A target gas with a response factor between zero and one implies that the device has a higher detector
response for that gas when compared to isobutylene. If the response factor is greater than one, the
device has a lower detector response for this gas when compared to isobutylene.
WARNING
It is very important to select the correct lamp setting during PID setup since PID response factors for
a target chemical relative to isobutylene are different depending on what energy PID lamp is
installed. See Chapter 4.5 for setup instructions. Failure to follow this warning can result in inaccurate
readings that could lead to serious injury or death.

The device has four gas alarms:
HIGH Alarm
LOW Alarm
STEL Alarm
TWA Alarm
-
US
Fig. 6
Alarm Conditions (here High Alarm)
The carbon monoxide channel in the device is equipped with an internal filter. The purpose of this filter
is to protect the CO sensor from acid gases (H2S, SO2, etc.) and from the hydrocarbons that the device
is intended to measure, including the calibration gas, isobutylene. In normal use, an interferent signal
for calibration or bump checking the device should not be observed on the CO channel. However,
exposure to large amounts of certain hydrocarbons (either long exposure times or high concentrations)
can overwhelm the filter and appear as signals on the CO channel.
In normal operation, after the hydrocarbon exposure is ended, the filter is designed to outgas absorbed
hydrocarbons at a rate that will not cause a signal on the CO channel. However, if the unit is exposed
to high temperature (>40°C), this desorption rate increases and spurious signals may be observed on
the CO channel due to gassing of previously absorbed hydrocarbons. Typically the CO sensor will

Description
recover within 24 hours but extremely high exposures can extend this time. After the recovery period
if the CO sensor can no longer be calibrated or shows an elevated reading that cannot be brought to
zero with a zero calibration, the CO sensor should be replaced.
If the gas concentration reaches or exceeds the alarm set point or the STEL or TWA limits, the:
- alarm message displays and flashes in combination with the corresponding gas concentration
- backlight turns on
- alarm sounds (if active)
- alarm LEDs flash (if active)
- vibrating alarm triggers (if active)
3.8
Monitoring Oxygen Concentration
The device monitors the oxygen concentration in ambient air. The alarm set points can be configured
to activate on two different conditions:
- Enriched - oxygen concentration > 20.8 vol % or
- Deficient - oxygen concentration < 19.5 vol %.
WARNING
If an alarm is triggered while using the device, leave the area immediately.
Remaining in the area under such circumstances can cause serious personal injury or death.
When the alarm set point is reached for either of the above conditions:
- the alarm message displays and flashes in combination with the corresponding gas concentration
- backlight turns on
- alarm sounds (if active)
- alarm LEDs flash (if active)
- vibrating alarm triggers (if active)
The LOW alarm (oxygen deficient) is latching and will not automatically reset when the O2 concentration rises above the LOW set point. To reset the alarm press the  button. If the alarm is latching, the
 button silences the alarm for five seconds. Alarms can be made latching or unlatching via MSA Link
software.
False oxygen alarms can occur due to changes in barometric pressure (altitude), humidity or extreme
changes in ambient temperature.
It is recommended that an oxygen calibration be performed at the temperature and pressure of use.
Be sure that the device is in known fresh air before performing a calibration.
3.9
Monitoring Combustible Gases
The device can be equipped with a catalytic combustible sensor that detects a variety of combustible
gases up to 100 % LEL and displays the reading as either % LEL or % CH4.
US
WARNING
If an alarm is triggered while using the device, leave the area immediately.
Remaining in the area under such circumstances can cause serious personal injury or death.
The catalytic combustible sensor has two alarm setpoints:
HIGH Alarm
LOW Alarm
If the gas concentration reaches or exceeds the alarm set point, the device:
- alarm message displays and flashes in combination with the corresponding gas concentration:
- backlight turns on
- alarm sounds (if active)

Description
Gas Exposure of 100 % LEL
When gas reading exceeds 100 % of the lower explosive limit (LEL), the device enters a Lock Alarm
state and displays “XXX” in place of the actual reading.
WARNING
A catalytic combustible gas reading of "XXX” indicates the atmosphere could be above 100 % LEL
and an explosion hazard exists. Move away from contaminated area immediately.
The user can clear the LockAlarm state only by turning the device OFF, and then ON again in a fresh
air environment. When catalytic combustible gas reading digits appear, the device is available for
measuring gases once again.
Check your national standard values for 100 % LEL.
3.10
Monitoring VOC Gases
The device is equipped with a PID sensor that detects a variety of VOC gases. The device displays
the gas concentration in parts per million (ppm), µmol/mol or mg/m3 on the Measuring page.
WARNING
If an alarm is triggered while using the device, leave the area immediately.
Remaining in the area under such circumstances can cause serious personal injury or death.
The device has four gas alarms:
- HIGH Alarm
- LOW Alarm
- STEL Alarm
- TWA Alarm
If the gas concentration reaches or exceeds the alarm set point or the STEL or TWA limits, the:
- alarm message displays and flashes in combination with the corresponding gas concentration
- backlight turns on
- alarm sounds (if active)
- alarm LEDs flash (if active)
- vibrating alarm triggers (if active)
To reset the alarm press the  button.
False VOC alarms can occur due to changes in barometric pressure (altitude), humidity or extreme
changes in ambient temperature.
It is recommended that a VOC calibration be performed at the temperature, humidity and pressure of
use.
Be sure that the device is in known fresh air before performing a calibration. For optimal lamp strike,
the PID lamp should be started within the normal temperature range.
US
When the device is calibrated in an dry, air conditioned environment and taken to a high
temperature and high humidity outdoor environment, a VOC Low or High alarm may be
triggered by this sudden change. It is recommended that the PID sensors be cleaned
prior to this transition to avoid this situation, or to acclimate the sensor to the outdoor
conditions in a known safe area.

Displaying Current Response Factor
The current Response Factor (RF) is displayed at device startup along with the PID lamp potential in
eV value, sensor range and VOC gas type.
During operations, the RF can be displayed through several menus. If the Menu Enable option is On,
use the  button on the Main Measuring page to scroll through the menu options and select YES on
"Change VOC Gas?". Selecting any gas on this page will display the 8 character gas name, the
Response Factor, the Maximum Value of the VOC gas and the current High and Low Alarm values.
The Maximum Value is calculated by multiplying the sensor range by the RF. For example, the
Max Value for Hexane is 2000 *4.5 = 9000 ppm. The maximum value cannot exceed 9999 ppm .
US
It is the responsibility of the user to change the VOC Low and High Alarms as appropriate
for the applied RF. The selection of the alarm limits must be under the direction of a
qualified safety professional who has carefully evaluated the specific hazards of the
jobsite where it will be used and who is completely familiar with the product and its limitations.
A complete list of the 8 character gas name and Response Factors for all VOC gases is contained in
chapter 10.

Operation
Device operation is dialog driven from the display with the aid of the three function buttons
(→ chapter 3.2).
For more information, see the flow charts in chapter 11.
4.1
Environmental Factors
A number of environmental factors may affect the gas sensor readings, including changes in pressure,
humidity and temperature. Pressure and humidity changes affect the amount of oxygen actually
present in the atmosphere.
Pressure Changes
If pressure changes rapidly (e.g., stepping through airlock), the oxygen sensor reading may temporarily
shift and possibly cause the device to go into alarm. While the percentage of oxygen may remain at or
near 20.8 Vol %, the total amount of oxygen present in the atmosphere available for respiration may
become a hazard if the overall pressure is reduced by a significant degree.
Humidity Changes
If humidity changes by any significant degree (e.g., going from a dry, air conditioned environment to
outdoor, moisture laden air), oxygen readings can be reduced by up to 0.5 %, due to water vapor in
the air displacing oxygen.
The oxygen sensor has a special filter to reduce the effects of humidity changes on oxygen readings.
This effect will not be noticed immediately, but slowly impacts oxygen readings over several hours.
Temperature Changes
The sensors have built-in temperature compensation. However, if temperature shifts dramatically, the
sensor reading could shift.
Combined Humidity and Temperature Changes
When the device is calibrated in an dry, air conditioned environment and taken to a high temperature
and high humidity outdoor environment, a VOC Low or High alarm may be triggered by this sudden
change. It is recommended that the PID sensors be cleaned prior to this transition to avoid this situation, or to acclimate the sensor to the outdoor conditions in a known safe area.

Sampling System Safety Test
Upon startup, an alarm (visual, audible and vibrating) is triggered and the customer is prompted to
block the pumps/sampling system of the device within 30 seconds.
When the device detects a pump flow block, it will display a PASS message. The startup sequence will
resume.
If the device does not detect a pump flow block, it will display an error message.
The device will shut OFF after the customer acknowledges this message by pressing the  button.
Check your sampling system if this occurs and contact MSA as needed.
Users can check the operation of the sampling system any time during operation by blocking the
sampling system to generate a pump alarm.
ALTAIR 5X PID
29
Operation
WARNING
Do not use the pump, sample line, or probe unless the pump alarm activates when the flow is
blocked. Lack of an alarm is an indication that a sample may not be drawn to the sensors, which
could cause inaccurate readings.
Failure to follow the above can result in serious personal injury or death.
Never let the end of the sampling line touch or go under any liquid surface. If liquid is drawn into the
device, readings will be inaccurate and device could be damaged. We recommend the use of an
MSA sample probe containing a special membrane filter, permeable to gas but impermeable to
water, to prevent such an occurrence.
Fresh Air Setup (FAS) at device Turn-ON
The Fresh Air Setup (FAS) is for automatic ZERO adjustment of the device.
The FAS has limits. If a hazardous level of gas is present, the device ignores the FAS command and
the device alarm activates.
The ability to perform an FAS at device turn-ON can be disabled by using MSA Link software.
WARNING
Do not perform the Fresh Air Setup unless you are certain you are in fresh, uncontaminated air;
otherwise, inaccurate readings can occur which can falsely indicate that a hazardous atmosphere is
safe. If you have any doubts as to the quality of the surrounding air, do not use the Fresh Air Setup
feature. Do not use the Fresh Air Setup as a substitute for daily calibration checks. The calibration
check is required to verify span accuracy. Failure to follow this warning can result in serious personal
injury or death.

Bump Test
WARNING
Perform a Bump Test before each day’s use to verify proper device operation. Failure to perform this
test can result in serious personal injury or death.
Bump test frequency is often stipulated by national or corporate regulations; however,
bump testing before each day’s use is generally the accepted best safety practice and
is therefore MSA’s recommendation.
This test quickly confirms that the gas sensors are functioning. Perform a full calibration periodically to
ensure accuracy and immediately if the device fails the Bump Test. The Bump Test can be performed
using the procedure below or automatically using the GALAXY GX2 Test Stand.
CSA requires (per 22.2 NO. 152) that combustible sensor sensitivity be tested before each day's use
on a known concentration of methane equivalent to 25 to 50 % of full scale concentration. ACCURACY
MUST BE WITHIN 0 to +20 % OF ACTUAL. Correct accuracy by performing the calibration procedure
described in chapter 4.10.
NOTE: The GALAXY GX2 cannot test the Chlorine Dioxide sensor. For this sensor, use this Bump Test
procedure and/or manually calibrate as described in chapter 4.10.
US
Equipment
See accessory chapter for ordering information for these components.
- Calibration Check Gas Cylinder(s)
See chapter 6.3 for calibration gas target values and appropriate MSA calibration gas cylinders.
- Demand Flow Regulator(s)
- Tubing appropriate for the gases to be tested
- Kits containing tubing and regulators suitable for reactive and non-reactive gases are available
from MSA.
ALTAIR 5X PID

Operation
Performing a Bump Test
When bumping a PID sensor, use 100ppm isobutylene balanced in air.
(1)
While the device is turned ON in a clean, fresh air environment, verify that readings indicate no
gas is present.
(2)
From the normal measure screen press the  button to display “BUMP TEST?”.
(3)
Verify the gas concentrations displayed match the Calibration Check Gas Cylinder. If they do
not, adjust the values through the Calibration Setup menu.
 Depending on the sensors installed, there could be one to five separate Bump Tests
performed, each with a different cylinder, regulator, and tubing used.
(4)
Attach the demand regulator (supplied in the calibration kit) to the cylinder providing the indicated gases.
(5)
Connect tubing (supplied in the calibration kit) to the regulator.
(6)
Attach the other end of tubing to the device pump inlet.
(7)
Press the q button to start the bump test:
 the progress bar advances
 the sensors respond to the gas.
The message BUMP TEST PASS indicates a successful Bump Test of the sensors.
If any sensor fails the Bump Test:
- the message BUMP TEST FAIL appears
- the failed sensor is indicated.
If there are more sensors to be Bump Tested, the next sensor displays and the process repeats from
Step 4.
If there are no more sensors to be Bump Tested, the tubing can be removed from the device pump
inlet.
After the Bump Test
After all installed sensors pass the Bump Test, the √ symbol displays on the MEASURE page. This
√ symbol appears on the display in the upper feature bar
If any sensor was not bump tested, or fails the Bump Test, the √ symbol does not display.
The color display:
- temporarily shows the √ symbol at each gas reading for successfully bump tested sensors
- √ symbol is then replaced by the present gas reading.
The √ symbol shows for 24 hours after the Bump Test.
If a sensor fails the Bump Test, calibrate the device as described in chapter 4.10.

4.10
Calibration
The ALTAIR 5X PID can be calibrated either manually using this procedure or automatically using the
GALAXY GX2 test stand. Refer to chapter 11.5.
The use of the demand regulators listed in chapter 9 is recommended. If a new sensor has been
installed, the battery pack has been depleted or a new battery pack has been installed allow sensors
to stabilize for 30 minutes before calibration is performed.
WARNING
Special conditions with toxic gases!
If the device is to be checked or calibrated for reactive gases, prerequisites are required; otherwise,
incorrect calibration would result in incorrect device operation.
Reactive toxic gases (e.g., chlorine, ammonia, chlorine dioxide) have the property of diffusing into
the rubber and plastic tubes so that the volume of test gas available in the device would no longer
be sufficient to correctly perform device calibration.
When calibrating the device with toxic gases, certain prerequisites are required, otherwise incorrect
calibration could result:
- A special pressure regulator
- Shortest possible connection tubes between the pressure regulator and the device
- Connection tubes made from a material that does not absorb the test gases (e.g., PTFE).
NOTE: If using normal tubes and pressure regulators, expose them to the required test gas for an
extended time period. Keep these materials dedicated for use with that test gas only; do not use them
for other gases.
For example, for chlorine, allow the entire contents of a test gas cylinder to flow through the pressure
regulator and tubes before using to calibrate the device. Mark these materials for use with chlorine
only.

Operation
Span Calibration
To skip the Span calibration procedure, push the  button.
If the SPAN calibration of the combustible sensor is skipped after a successful ZERO
calibration, the combustible sensor reading may be replaced with a moving display of
“PLEASE WAIT” for a few moments. This is normal, and the device is fully operational
once a combustible gas reading reappears.
If no button is pushed for 30 seconds, span calibration is skipped.
Because of the different possible combinations of gases that are possible, skipping a Span calibration
could advance the user to the Span calibration of another installed sensor, or back to Measuring mode.
When calibrating a PID sensor, use 100 ppm isobutylene balanced in air. Isobutylene
calibration gas greater than 100 ppm is not allowed due to long term affect on the
CO sensor.

Operation
If a sensor is nearing its end-of-life, the "PASS" display is followed by the Sensor Life indicator
♥ display.
- While the sensor is still fully functional, this warning gives the user time to plan for a replacement
sensor to minimize downtime.
- The ♥ indicator blinks as the device returns to Measure mode.
- After 15 seconds, the blinking stops, but the ♥ indicator continues to display during ongoing operations as a reminder of a sensor’s pending end-of-life.
If a span calibration fails:
- The Sensor Life Indicator ♥ blinks to show a sensor has reached its end-of-life and should be
replaced.
- The device remains in the Sensor Life alarm condition until the  button is pressed.
- After the alarm is cleared, the device enters Measure mode and the Sensor Life indicator ♥ blinks
during ongoing operations until the sensor is replaced and/or successfully calibrated.
Span calibration can fail for reasons other than a sensor at the end of its life. If a span calibration failure
occurs, verify items such as:
- sufficient gas remaining in the calibration cylinder
- gas expiration date
- integrity of calibration tubing/fittings, etc.

Reattempt the span calibration before replacing the sensor.
Finishing Successful Calibration
(1)
Remove the calibration tube from pump inlet.
The calibration procedure adjusts the span value for any sensor that passes the calibration test.
Sensors that fail calibration are left unchanged.
On the color display, each successfully calibrated sensor temporarily shows a √ symbol at its gas
reading.
These √ symbols remain visible for a few moments and are then replaced by the present gas reading.
Since residual gas may be present, the device may briefly go into an exposure alarm after the calibration sequence is completed.

Press the  button to reset the alarm as necessary.
Following a PID sensor calibration, VOC gas readings may be slightly elevated (< 5 ppm) for several
minutes. This is normal behavior as the isobutylene is purged from the device.
A √ symbol displays on the MEASURE page.This √ symbol appears on the:

Verifying Pump Operation
Users can check operation of the sampling system any time during operation by blocking the sampling
system to generate a pump alarm.
When the pump inlet, sample line or probe is blocked, the pump alarm must activate.
Once gas readings are displayed, plug the free end of the sampling line or probe.
- The pump motor shuts down and an alarm sounds.
- PUMP ERROR will flash on the display.

Press the  button to reset the alarm and restart the pump.
If the alarm does not activate:
- Check the sample line and probe for leaks.
- Once leak is fixed, recheck pump alarm by blocking the flow.

Press the  button to reset the alarm and restart the pump.
WARNING
Do not use the device, sample line, or probe unless the pump alarm activates when the flow is
blocked. Lack of an alarm is an indication that a sample may not be drawn to the sensors, which
could cause inaccurate readings. If a sample line or probe is installed and the pump alarm does not
activate, remove the line or probe and repeat the test. This will provide information on where the
blockage is located.
Failure to follow the above can result in serious personal injury or death.
Never let the end of the sampling line touch or go under any liquid surface. If liquid is drawn into the
device, readings will be inaccurate and device could be damaged. We recommend the use of an
MSA sample probe containing a special membrane filter, permeable to gas but impermeable to
water, to prevent such an occurrence.
During operation, a pump alarm may occur when the:
Flow system is blocked
Pump is inoperative
Sample lines are attached or removed.

Background Information
The sensor's rugged, durable design provides for trouble-free operation over the course of its lifetime.
However, in certain conditions, maintenance may be required. This is customer required maintenance
and is not covered under warranty.
Parts that may need cleaning or replacing over time include the UV Lamp, Cell Assembly, Teflon Filter,
Cotton Filter, Cap, and Spacer. See Recommended Supplies section above.
Over time when the sensor is exposed to harsh chemicals or in a polluted environment, lamp window
contamination can occur. This will degrade the sensor's performance. The contamination will block
some of the UV light and decrease the sensors gain.

PID Response Factor Table

PID Response Factor Table
WARNING
VOC Response factors apply in the 0-500 ppm range. The values in this table were obtained using
dry bottled gases at room temperature. The response factors may change at higher concentrations,
different temperature and humidity conditions, or with cleanliness of lamp. For increased accuracy
at different ambient conditions or concentrations, determine a custom response factor and enter it
via the Custom Gas page; see Chapter XX, Custom Gas Setup. These response factors are specific
to the energy of the lamp designated in the table. They are not valid for devices using PID lamps at
any other energy. Using these response factors with a lamp at any other energy may critically
compromise the device's ability to detect volatile organic compounds which can result in serious
personal injury or death.
WARNING
Use of Altair5X PID for detection of extremely toxic gases:
The system resolution limit of the Altair5X PID in normal mode (with a new, clean lamp) is approximately 0.1 ppm isobutylene equivalent. Users must be aware of exposure limit guidelines, such as
TLV, for the target compound. Do not use the Altair5X PID Detector if the exposure limit for the target
compound is below 0.1 ppm. Failure to follow this warning can cause over-exposure, which can
result in serious personal injury or death.
For any compound, its exposure limit guideline can be recalculated in terms of equivalent ppm isobutylene by dividing the exposure limit guideline by the appropriate response factor. Example: For
butyl acetate (CAS 123-86-4), the recommended threshold limit value (as TWA) is 150 ppm. Its
response factor (10.6 eV lamp) is 2.4. The TLV for butyl acetate, in terms of equivalent ppm isobutylene is: 150 ppm ÷ 2.4 = 62.5 ppm isobutylene equivalent.
WARNING
The ALTAIR 5X PID Detector has a reproducibility of ±2 ppm(± 2000 ppb) or 10%, whichever is
greater (see table in chapter 6.2).The user must account for this potential variation between the
displayed value and the actual concentration when setting alarms and interpreting readings. Failure
to comply with this warning can cause over-exposure and result in serious personal injury or death.
Gases with very high response Factors (RF):
The Altair5X PID is a very versatile solution for monitoring many different gases and vapors. In addition
to the pre-programmed list provided in the Altair5X PID device, users can determine response factors
for many other compounds (see Section X). The maximum response factor value that will be accepted
by the Altair5X PID device is 39.99.
US
WARNING
Use the correct lamp when determining the response factor. Failure to apply the appropriate
response factors can result in inaccurate readings, and serious injury or death can occur.
