AQ700 Multi-Parameter Sonde
Section 1 Introduction
1.1 Overview
The AQ700 Sonde is designed to monitor from one to ten water
quality parameters for the purpose of sampling, analysis, and
process control.
The sonde’s ease-of-use design includes direct USB connection to
your computer, real-time data viewing, and LED indicators for
operating status.
Using SDI-12 protocol, the AQ700 can connect to the following
Teledyne Isco instruments:
• 6712 or Avalanche® Sampler
• Signature® Flow Meter
• 2105 Interface Module
1.2 Connecting to
Teledyne Isco Devices
Sensor field cables are available in 3 different lengths:
• 5 meters
• 10 meters
• 15 meters
The AQ700 field cable connects to a Teledyne Isco sampler, flow
meter, or logging device with the appropriate SDI-12 adapter.
Parameter measurements are always for the current sonde configuration.
Note
The adapter identifies the connected sonde at power-up only,
and will not acknowledge a sonde replacement or parameter
change until it is powered on and off.
BEFORE connecting/disconnecting the SDI-12 adapter from
the AQ700 sonde: Disconnect the SDI-12 Adapter from the
sampler or 2105; disconnect power from the Signature.
Table 1-1 on the following page shows the devices that can be
used with the AQ700, as well as the appropriate device connectors for operation with the AQ700.
6712/Avalanche
connection
All sonde connections/disconnections must be made with the
SDI-12 adapter disconnected from the sampler.
With the SDI-12 adapter disconnected, select NO SDI-12
SONDE and accept NEW HARDWARE SETUP to clear the previous sonde configuration. After connecting the AQ700 to the
adapter, connect the adapter to the sampler and perform a scan
to access the AQ700 parameters.
1-1
AQ700 Multi-Parameter Sonde
Section 1 Introduction
Signature connection
All sonde connections/disconnections must be made with the Signature disconnected from power. With the Signature’s power disconnected, connect the new (or newly configured) sonde to the
adapter. After the Signature’s power is restored, you must use
the Signature program screen to delete the old sonde from the
system, then scan for and add the currently connected sonde to
the Active Sondes window, and Configure. Refer to your Signature user manual for complete programming steps.
The Signature will not display the software version of the
adapter.
2105 Connection
All sonde connections/disconnections must be made with the
SDI-12 adapter disconnected from the module.
The software version of the adapter will not appear in Flowlink.

1. The sampler will
automatically refer to depth as
"level." If another level-sensing
device is connected to the
sampler, that device’s
measurements will by default be
used for flow conversion. If no
other level-sensing device is
connected it is recommended
that the sampler be
programmed to record "Level
Only."

Section 3 Sensors and Calibration
3.1 Overview
The instructions in this general section apply to all sensor types.
Calibration procedures specific to each sensor type are provided
later in this section.
Keep in mind that measurement accuracy is only as good as the
calibration standard used and adherence to the calibration procedure. Never use a solution that has expired, and always wait
for the readings to stabilize before saving a calibration.
3.1.1 When to Calibrate
The frequency of calibration depends largely on your accuracy
requirements and site conditions.
Frequent calibrations normally yield better data—particularly if
the AQ700 is used across multiple ranges of water conditions. To
determine whether or not calibration is needed, check your
sensor against a known sample. If the reading falls within the
sensor’s specification and/or your requirements, calibration is not
necessary.
Replacement of any sensor or reference solution should be followed by calibration.
3.1.2 General Calibration
Procedures
Prior to calibration, ensure that the AQ700’s sensors are all clean
and well-maintained.
1. Select a calibration standard with a value similar to what
you expect to measure in the field. For best results, use
fresh calibration standards, discarding them after one use.
Note
Do not calibrate using a seawater standard.
Note
If the water you are monitoring tends to be acidic, calibrate
your pH sensor with a buffer of 4 rather than 10.
2. Thoroughly rinse the sensors, as many times as necessary,
with deionized water, especially if they have been submerged in other calibration solutions. Shake the AQ700
vigorously to shake off remaining traces of solution.
3. Rinse the sensors twice with a small amount of the calibration standard. Discard the used calibration standard.
4. Remove the cap from the calibration cup and screw the cup
onto the end of the AQ700. Turn the sonde upside-down,
and pour the calibration standard into the cup, making
3-1
AQ700 Multi-Parameter Sonde

sure all sensors are completely covered, including the
thermistor (for parameters that are temperature-compensated).
Note
Do not put the cap on during calibration.

b. Click Calibrate, then select the desired parameter from
the drop down list.
c. Type in the value of the calibration standard and press
Enter.
d. Wait for the reading to stabilize. Press Enter to calibrate.
6. If not installing the AQ700 right away, thoroughly rinse
the cup and sensors, then refill the cup with tap water and
screw the cap back on.

Section 3 Sensors and Calibration
3.1.3 Sensor Response
Factor (SRF)
The term Sensor Response Factor (SRF) refers to the value displayed at the end of the calibration, indicating whether or not
your calibration was acceptable. An SRF between 60% and 140%
is considered acceptable.
If the SRF is outside this range, ensure that conditions are
acceptable for this calibration:
• Wait for the reading to fully stabilize before pressing
Enter.
• Ensure that the sensor is clean.
• Ensure that the calibration standard is the correct value
and is not contaminated.
If you click OK, regardless of whether or not the SRF is within
the acceptable range, the calibration will be stored, and you will
be returned to the main screen. If you click Quit, the calibration
will not be stored.

3.4.2 Set Barometric
Pressure (BP)
The Barometric Pressure value impacts the HDO % saturation
value. The Set Barometric Pressure window can be accessed
either directly from the Calibrate menu, or via the Calibrate >
HDO screen > BP.
The BP can be set using one of three methods.
Enter BP (mm/Hg)
This method is mainly used in short-term testing where you may
want to correct for effects of current weather.
Enter the actual BP in mm/Hg in the first field. When this value
is entered, the elevation will automatically appear in the second
field.
Note
Keep in mind that the barometric pressure reported by the
local airport will be corrected for sea level. The value you enter
for calibration must not be corrected for sea level.
Enter elevation (ft)
This is the most accurate method if you are calibrating off-site
before taking the sonde to the installation site.
Enter the elevation in feet in the second field. When this value is
entered, the BP will automatically appear in the first field.
Read BP (depth sensor)
This is the most accurate method if you are calibrating on-site.
Remove the calibration cup from the AQ700 and make sure the
depth sensor is exposed to the open air. The correct values will
automatically appear in the BP and elevation fields.
Figure 3-9 Setting the barometric pressure
3-7
AQ700 Multi-Parameter Sonde
Section 3 Sensors and Calibration
3.4.3 Temperature Sensor
The temperature sensor is a thermal electrical
resistor (thermistor), whose resistance changes
predictably with the temperature. The sensor is
protected by a stainless steel tube.
Thermistors do not require calibration.
3.4.4 Dissolved Oxygen (DO)
Sensor
The optical DO sensor comprises a blue light source, a sensing
surface, and a red light receiver. The sensing surface is an
oxygen-active compound stabilized in an oxygen-permeable
polymer. When the sensing surface is exposed to water (or air),
oxygen diffuses into the sensing surface according to the amount
of oxygen in the water.
The oxygen-active compound fluoresces (absorbs energy in the
form of blue light and emits energy in the form of red light). The
blue light pulses once for each measurement cycle. The receiver
measures the duration of the fluorescence following the pulse.
This measured duration is proportional to dissolved oxygen.
The sensor output is corrected for temperature characteristics of
both the membrane and of oxygen saturation in water.
Note that the optical DO sensor does not consume oxygen. Consequently, an oxygen-active fouling, such as algal growth, may
cause exaggerated reports of oxygen data. Consider this factor
when selecting the installation site and calculating how often to
clean the sensor (refer to Routine Cleaning, page 4-1).
3.4.5 DO: Calibration
If your AQ700 is using a DO sensor, it must know the correct
barometric pressure. Always verify that the BP is correct prior to
DO calibration. From the Calibrate menu, select HDO % Sat. If
the BP displayed in Hg is incorrect, click the BP button to get to
the Set Barometric Pressure window.
Figure 3-10 DO Measurement: Verifying correct barometric pressure
3-8
AQ700 Multi-Parameter Sonde
Section 3 Sensors and Calibration
Then perform the following steps.
1. Pour 0.5 L of tap water in a 1L jar, seal the lid, and aerate
the water by shaking the jar vigorously for one minute.
2. Remove the lid, and let the water stand for about five minutes to allow the air bubbles to escape.
3. Screw the calibration cup onto the end of the sonde, and
turn the sonde upside-down. Fill the cup with the aerated
water, ensuring that the DO and temperature sensors are
completely covered.
4. Allow ten minutes for equilibration. Then follow “General
Calibration Procedures” on page 3-1, using % sat.
3.4.6 DO: Zero-DO
Verification
Although the AQ700 software does not support zero-DO calibration, the sensor’s zero-DO reading can be verified using
nitrogen gas.
Simply seal the sensor end of the AQ700 in a plastic bag, ventilated with a small hole, and feed nitrogen gas into the bag.
Note
If you are using a high-pressure gas tank, use a two-stage regulator.
3.4.7 Conductivity Sensor
The AQ700’s conductivity sensor uses two pairs of
graphite electrodes to determine water conductivity. A constant voltage is applied to one of each
pair, and the amount of current required to
maintain that voltage is measured. The current
will increase or decrease in proportion to the
water conductivity.
T h e A Q 7 0 0 r e p o r t s S p e c i f i c C o n d u c t a n c e,
meaning the sensor performs a measurement
standardized to a water temperature of exactly
25°C.
The conductivity value can be used to calculate
the custom parameters Total Dissolved Solids (TDS) or salinity.
3.4.8 Conductivity:
Calibration
Choose a calibration solution that best addresses the range of
values expected at the site.
The best accuracy is achieved at measurement values closest to
the calibration point.
Screw the calibration cup onto the end of the AQ700 and fill it
with the conductivity standard, ensuring that the sensor is completely covered. Gently tap on the cup to make sure no bubbles
are trapped in the sensor.
The conductivity sensor’s zero point is set electronically, so you
only have to set the “slope” point.
Follow the instructions in “General Calibration Procedures” on

Section 3 Sensors and Calibration
3.4.9 pH Sensor
pH is measured as a voltage drop between a
glass membrane containing an electrolyte,
and a reference electrode. The glass voltage
changes in response to changes in the ionic
c o n c e n t r a t i o n o f t h e wa t e r, w h i c h i s
proportional to the pH level. This change in
voltage potential is converted into the pH
reading.
pH readings are automatically compensated
for temperature.
3.4.10 pH: Calibration
When a pH calibration is performed, all previous calibration
information will be erased. Therefore, if the sensor was previously calibrated with three buffers, a two-point calibration would
erase all of the third point data, and the two-point calibration
would be used from then on.
A two-point calibration generally uses a seven buffer, and a
second buffer with a value near that of the waters you intend to
monitor.
1. Rinse the sensors several times with the pH calibration
buffer.
2. Fill the calibration cup with enough buffer to cover both
electrodes.
3. Follow “General Calibration Procedures” on page 3-1 for
pH units.
4. Repeat these steps for each calibration standard.
3.4.11 Oxidation-Reduction
Potential (ORP) Sensor
ORP is measured as the voltage drop
across the platinum membrane of an
electrode. A reference electrode
completes the measuring circuit.
The ORP sensor appears as a tiny, silver
dot viewed when looking down at the pH
sensor.
3.4.12 ORP: Calibration
ORP uses a one-point calibration.
1. Rinse the sensors several times with the ORP calibration
standard.
2. Fill the calibration cup with enough ORP standard to cover
the electrodes.
3. Follow the instructions in “General Calibration Procedures” on page 3-1 for ORP mV.
3.4.13 Depth Sensor
3-10
The depth sensor has an internal pressure transducer.
AQ700 Multi-Parameter Sonde
Section 3 Sensors and Calibration
T h e h y dro st at i c pre ssur e e xert e d o n t h e t r a n sd uce r is
proportional to its distance below the surface of the stream.
Depth should not be used as a measure of the water level. Depth
is not recommended as a factor for flow conversion.
3.4.14 Depth: Calibration
Depth calibration consists of simply allowing the reading to zero
while the sensor is in the open air. Make sure the calibration cup
is not installed.
1. Ensure that the sensors are in open air and not in water.
2. Select the parameter to be calibrated.
a. Click the AQ700 pull down menu.
b. Click Calibrate, then select “Depth m” or “Depth ft”
from the drop down list.
c. Allow the depth reading to stabilize and click OK.
3.4.15 Turbidity Sensor
Turbidity is measured as the fraction of an
infrared light beam scattered at 90° to that beam.
More particles in the water means more light
scattered, making the turbidity reading higher.
Any material that accumulates on the optical
surface of the sensor is indistinguishable from
material in the water; therefore, the sensor has a
small wiper to periodically clean the window.
The wiper activates once when the SDI-12 converter first powers up, and then once before each
reading is taken.
Turbidity sensors require no regular maintenance, other than
occasional inspection of the optical window and wiper to ensure
that they are still clean and undamaged. A clogged or
deteriorated wiper pad can lead to a dirty window. For wiper pad
replacement instructions, refer to Turbidity Sensor: Wiper, page
4-3.
3.4.16 Turbidity: Calibration
Turbidity calibration consists of two points: One point is zero turbidity (de-ionized water), and the other should be a standard
approximating the turbidity of the water you intend to monitor.
Standards made for drinking water should not be used.
Polymer-bead calibration solutions are recommended for their
stability and safety. For best results, use the same type of calibration standard every time.
Note
Unlike the other sensors, the turbidity sensor should not be
calibrated using the AQ700’s calibration cup, as the sensor
requires a larger optical sensing field than the cup allows.
3-11
AQ700 Multi-Parameter Sonde
Section 3 Sensors and Calibration
Note
Ensure that the sensor’s optical sensing
field (about the volume of a tennis ball) is
free of obstruction and untouched by light.
The calibration solution is typically kept in a
dark-colored, one-liter, wide-mouth bottle
with a non-reflective finish to ensure that
t h e s e n s o r ’s o p t i c a l f i e l d i s f r e e o f
interference from container walls or other
objects, and/or light scatter.

Section 4 Maintenance, Troubleshooting, and
Servicing
4.1 Routine Cleaning
To keep the AQ700 Sonde in optimal condition, clean it periodically with warm water, a soft cloth, and dish soap. Clean the
sensor stems with a soft brush.
CAUTION
Never use abrasives, acetone, gasoline, kerosene, or industrial
cleaners.
Rinse thoroughly with tap water. Store the sensors in the storage
cup filled with tap water.
4.2 O-Ring Lubrication
Whenever the calibration/storage cap or field cable is removed,
re-apply silicone grease to the exposed o-rings. Apply the grease
generously, in particular to the o-rings of the field cable connector. Silicone grease is included in the maintenance kit.
CAUTION
Only use silicone grease. Other kinds of lubricants may chemically attack the o-ring.
Figure 4-1 Periodic Maintenance: Grease the o-rings
4-1
AQ700 Multi-Parameter Sonde
Section 4 Maintenance, Troubleshooting, and Servicing
4.3 pH & ORP: Reference
Electrode
For continued reliable measurement, the pH and ORP reference
electrolyte should be replaced every 1 to 2 months, depending on
the type of water you are monitoring.
The maintenance kit that comes with the AQ700 includes a
120 mL. bottle of electrolyte.
1. Unscrew the reference cap from the sleeve and discard the
old electrolyte.
2. Fill the sleeve completely with fresh electrolyte, taking
care not to introduce any air bubbles.
3. Screw the reference cap back onto the sleeve.
Figure 4-2 pH and ORP: Changing the electrolyte
As you screw the sleeve into place, the excess electrolyte is forced
out through the reference electrode junction (white, porous circle
at the end of the sleeve). This helps to purge air from the electrolyte, and cleans residue out of the junction.
4.4 DO Sensor Tip
The tip of the optical DO sensor must be replaced periodically,
i.e., usually every few years.
The need for replacement is usually indicated by erratic
readings. Simply unscrew the old tip, screw in a new one, and
recalibrate the sensor.

4.5 Turbidity Sensor:
Wiper
A clean wiper means better measurements. If the wiper is deteriorated or clogged with debris, it can be cleaned or replaced.
The AQ703 maintenance kit contains a replacement wiper and
1.5 mm Allen wrench.
CAUTION
Never rotate the wiper arm manually; doing so will cause serious damage to the sensor.
To clean or replace the turbidity wiper:
1. Using the Allen wrench, loosen the set screw on the wiper,
and remove it from the motor shaft.

b. Clean the arm and contact with warm water and a soft
brush or cloth.
c. Push the contact all the way back into the arm, making
sure the pointed side of the contact is on the flanged
side of the arm.

3. Gently press the wiper toward the face of the probe until
the rubber contact is compressed to roughly 3/4 of its original thickness.
CAUTION
Do not let the wiper arm touch the probe face. Only the contact
should touch.
The gap is correctly set if you can slide a sheet of paper
under the contact, but the contact will still hold the paper
in place.
4. Tighten the set screw until normal resistance is felt.
CAUTION
Do not over-tighten the set screw; this will strip the wiper’s
plastic threads.

The warranty for any probe is the one in effect on date of

maintenance. This warranty does not cover products not
sold under the Teledyne Isco trademark or for which any
other warranty is specifically stated.
No item may be returned for warranty service without a
return authorization number issued by Teledyne Isco.
This warranty is expressly in lieu of all other warranties
and obligations and Teledyne Isco specifically disclaims
any warranty of merchantability or fitness for a

This warranty exclusively covers Teledyne Isco multiparameter probes, providing a two-year limited warranty
covering parts and labor.
Any probe that fails during the warranty period due to
faulty parts or workmanship will be repaired at the factory
at no charge to the customer. Teledyne Isco’s exclusive
liability is limited to repair or replacement of defective
probes. Teledyne Isco is not liable for consequential
damages.
Teledyne Isco will pay surface transportation charges both
ways within the 48 contiguous United States if the probe
proves to be defective within 30 days of shipment.
Throughout the remainder of the warranty period, the
customer will pay to return the probe to Teledyne Isco, and
Teledyne Isco will pay surface transportation to return the
repaired probe to the customer. Teledyne Isco will not
pay air freight or customer’s packing and crating charges.
This warranty does not cover loss, damage, or defects
resulting from transportation between the customer’s
facility and the repair facility.

* This warranty applies to the USA and countries where Teledyne Isco does not have an authorized dealer.
Customers in countries outside the USA, where Teledyne Isco has an authorized dealer, should contact their
Teledyne Isco dealer for warranty service.
Before returning any probe for repair, please call, fax, or e-mail the Teledyne Isco Service
Department for instructions. Many problems can often be diagnosed and corrected over the
phone, or by e-mail, without returning the probe to the factory.
Probes needing factory repair should be packed carefully, and shipped to the attention of the
service department. Small, non-fragile items can be sent by insured parcel post. PLEASE BE
SURE TO ENCLOSE A NOTE EXPLAINING THE PROBLEM.
