1.1 Introduction
The OS550A Series Industrial Infrared (IR) Thermometers provide
non-contact temperature measurement up to 4500°F (2482°C).
They offer effective solutions for many non-contact temperature
applications, including the following:
• Predictive Maintenance: Tracking temperature shifts which
indicate pending failure in solenoid valves.
• Energy Auditing: Locating wall insulation voids to reduce
building heating costs.
• Food Processing: Taking accurate temperature readings
without direct contact with the food or packaging material.
• Annealing Processing: Monitoring surface temperatures
of metals while it is inside an oven by seeing through glass
window.
The IR thermometer provides a custom backlit dual digital LCD
that displays both current and minimum, maximum, average or
differential temperatures. This versatile instrument provides:
• Measurable target distances from 5 inches (12.7 cm) to
approximately 200 feet (61 m)
• Emissivity adjustable from 0.1 to 1.00 in 0.01 steps provides
ease of use when measuring a variety of surfaces.
• Continuous temperature measurement up to 10 times per
second.
• Audible and visual alarms. The high and low alarm points
are set via the keypad.
• Analog output, 1 mV/degree, 4-20mA or 0-5VDC
which allows interfacing with data acquisition equipment
(including chart recorders, data loggers and computers)
• Two way RS232 serial communication to a PC. This allows
downloading data for further analysis (OS552A, OS553A
and OS554A, OS555A).
• Ambient target temperature compensation. This provides
more accuracy for measuring low emissivity targets.
• Record up to 800 temperature data points either continuos or
on demand. Review the recorded data on the thermometer
LCD, as well as downloading the data to a PC (OS553A and
OS554A, OS555A).
• Backlit display useful in low ambient light conditions
• Laser Sighting is optional.
• High and Low Alarm outputs to drive external Mechanical
Relays

3.4 Measurement Techniques
You can use the IR Thermometer to collect temperature data in any
one of five different ways:
• Spot Measurement — Measures the temperature of discrete objects
such as motor bearings, engine exhaust manifolds, etc.:
1. Aim the sensor head at the desired target.
2.If necessary, adjust the emissivity using the
3. Read the temperature.
and
keys.
• Differential Measurement — Measures the temperature differential
between two spots (the maximum and minimum temperatures viewed)
1.Aim the thermometer at the first spot.
2. If necessary, adjust the emissivity.
3. Aim at the second spot.
4. Adjust the emissivity of the second spot if required.
5. To display the differential temperature, press the
key until
“dIF” appears on the display.
6. Read the differential temperature from the upper display.
• Static Surface Scan – M
easures the temperature across a static surface:
1.Aim the thermometer’s sensor head at a starting point.
2.
If necessary, adjust the emissivity.
3.Slowly move the thermometer’s sensor head so that the line of
sight sweeps across the surface. The thermometer measures the
temperature at each point on the surface.
4.To record the temperature profile across the surface, connect
the IR thermometer to a strip chart recorder that will accept an
analog input matching the analog output of the model OS550
that you have selected.

Laser Sight Accessory
4.2 Description
A laser sighting accessory is available to aid in the sensor head
installation process. When installing a line of sight Infrared
transducer with a small spot size and long target distance, it is
sometimes difficult to locate the center of the focused spot and the
material to be measured. To solve this problem, we offer a laser
sighting accessory OS550-LS that will install onto the front of the
OS550 series sensor head. This compact tool provides the installer
with a true line of sight laser dot up to a distance of 12.2 meters
(40’) in the center of the IR optical path taking the guess work out of
proper alignment during the installation. The laser is powered by a
power pack with replaceable batteries and interconnect cable.

5.1 Cleaning the Sensor Head Lens
Although all lenses are quite durable, take care to prevent scratching
when cleaning them. To clean the lens:
1. Blow off loose particles, using clean air.
2. Gently brush off remaining particles, using a camel hair brush.
Alternatively, clean any remaining contaminants with a damp, soft,
clean cloth. Be careful not to rub too hard.
CAUTION
Do not use any ammonia or cleaners with ammonia on the lens,
as damage may result. Do not wipe the surface dry, as this may
cause scratching.
5.2 Calibrating the Thermometer
The thermometer can not be calibrated by the user. For precise
calibration of the thermometer, call our Customer Service

Thermal Radiation
Heat is transferred from all objects via radiation in the form of
electromagnetic waves or by conduction or convection. All objects
having a temperature greater than absolute zero (-273°C, -459°F,
0 K) radiate energy. The thermal energy radiated by an object
increases as the object gets hotter. Measurement of this thermal
energy allows an infrared thermometer to calculate the object’s
temperature if the emissivity (blackness) is known. Generally, it is
convenient to measure the amount of radiated energy in the infrared
part of an object’s radiation spectrum.
Figure A-1 shows a block diagram of an infrared radiation
thermometer. Energy from the object is focused by the lens onto
the detector. As the detector heats up, it sends out an electrical
signal, which in turn is amplified and sent to the circuitry of
the thermometer. The thermometer software then calculates the
temperature of the object.

Appendix: How Infrared Thermometry Works
Blackbody
When thermal radiation falls on an object, part of the energy
is transmitted through the object, part is reflected and part is
absorbed. A blackbody is defined as an ideal object that absorbs
all the radiation incident upon it. The best example of a real object
that acts like a blackbody is a small hole drilled deep into a large
opaque cavity. Thermal radiation entering the cavity is internally
reflected and has little chance of escaping the cavity before it is fully
absorbed.
Emissivity is defined as the ratio of energy radiated by an object
to that of the energy radiated by a blackbody. By definition, the
emissivity of a blackbody is 1. Most objects are considered gray
objects with an emissivity between 0 and 1. Various emissivities for
common materials are shown in Appendix B.
Spectral Distribution
Objects radiate energy at different wavelengths, but not with
constant intensity at each
wavelength. Figure A-2
shows the energy radiated
by a blackbody at various
temperatures as a function
of wavelength. As a body
is heated, the intensity
of the radiated energy
increases and the peak of
the curve shifts towards
the shorter wavelength
end of the spectrum.
The total area under a
spectral distribution curve
is proportional to the
total energy radiated by
the blackbody at a given
temperature.
Figure A-2. Blackbody
Spectral Distribution
A-2
Relative emission from a blackbody versus wavelength.
The area under the curve corresponds to the total
energy, and is proportional to the absolute temperature
to the 4th power. The peak of the spectral distribution
curve shifts to shorter wavelengths as the temperature
increases.
Appendix: How Infrared Thermometry Works
A
Wien’s Displacement Law describes the exact mathematical
relationship between the temperature of a blackbody and the
wavelength of the maximum intensity radiation.
where λm = wavelength measured in microns
T = temperature in Kelvin
Calculating Temperature
The net thermal power radiated by an object has been shown to
depend on its emissivity, its temperature and that of the ambient
temperature around the object. A very useful equation known today
as the Stefan-Boltzmann Law has been shown both theoretically and
empirically to describe the relationship.
I = thermal power in watts/meter2
ε = Emissivity
σ = 5.6703 x 10-8 watts/meter2 x K4 (Stefan’s constant)
T = temperature of object in Kelvin
Ta = temperature of ambient surroundings in Kelvin
The infrared thermometer uses this equation directly in calculating
the temperature of an object. The incident power is measured by the
infrared detector. The emissivity of the object is determined by the
user. The ambient temperature is measured by a sensor inside the
thermometer. With all quantities known, the thermometer uses the
Stefan-Bolzmann Law to calculate and output the temperature of the
object

Appendix: How Infrared Thermometry Works
Optics Field of View
Accurate measurement of temperature via infrared means depends
strongly on the size of the object and the distance between the
thermometer and the object. All optical devices (e.g. cameras,
microscopes, infrared thermometers) have an angle of vision,
known as a field of view or FOV, within which they see all objects.
In particular, the thermometer will measure a fixed proportion of
the energy radiated by all objects within its FOV. The user must
guarantee that the distance between the thermometer and the object
is defined so that only that object fills the FOV of the instrument.
Referring to Figure A-3, Objects “X” and “Y” are within the FOV of
the thermometer. The measured temperature would fall somewhere
between the actual temperatures of the two objects. In order to
measure the temperature of Object “X” accurately, Object “Y” would
need to be removed. In order to measure the temperature of Object
“Y” accurately, the user would need to move closer to Object “Y”
until it completely filled the FOV of the thermometer. Alternatively,
the user could measure the temperature of Object “Y” with a
thermometer with a smaller FOV.
Figure A-3.
Field of View of a Thermometer/Transmitter
The distance-to-spot size ratio (D⁄S) defines the field of view (FOV).
Thus, a D⁄S = 10 gives you approximately a 1' spot size at a distance
of 10’. For accurate spot size values, refer to the Field of View
diagrams shown in Figures 3-3 through 3-8.

Appendix: Emissivity Tables
B
Table B-1 provides guidelines for estimating the emissivity of various
common materials. Actual emissivity, especially of metals, can vary
greatly depending upon surface finish, oxidation, or the presence of
contaminants. Also, emissivity or infrared radiation for some materials
varies with wavelength and temperature. To determine the exact
emissivities for most applications, follow the procedures in Appendix C.

Appendix: Determining an Unknown Emissivity
C
In Appendix A, we showed how emissivity is an important
parameter in calculating the temperature of an object via infrared
means. In this section we discuss how to determine a specific
emissivity value. If you know the material of the object, use Table
B-1 in Appendix B to look up its approximate emissivity. Most
organic materials such as plastics, cloth, or wood have an emissivity
of about 0.95. For this reason, we use 0.95 as the default emissivity
setting in the OS550A Series thermometers.
For objects of unknown material or for very precise measurements,
use one of the following methods to determine a specific emissivity
value.
Method 1
1.
2.
3.
Measure and record the temperature of the object using a contact
temperature probe such as a thermocouple or RTD.
Aim the thermometer at the object.
Adjust the emissivity until the temperature reading of the
thermometer equals the temperature measured in Step 1.
Method 2
1.
2.
3.
Heat the object (or at least a sample of the object material) on
top of a heating plate to a known temperature. Make sure the
thermometer and the air surrounding the heating plate are at the
same temperature.
Measure the temperature of the object material with the
thermometer. Make sure that the object fills the FOV of the
thermometer.
Adjust the emissivity until the temperature reading of the
thermometer equals the known temperature of Step 1.

sample of the object material). Allow time for the masking tape to
reach the object temperature.
Set the emissivity of the thermometer to 0.95. Use the thermometer
to measure and record the temperature of the masking tape - Area
“A” in Figure C-1. Make sure that the area of the object covered
with masking tape fills the FOV of the thermometer.

Paint a sample of the object material with flat black lacquer paint.
Set the emissivity to 0.97 and measure and record the temperature
of the painted portion of the sample material - Area “A” in Figure
C-1. Make sure that the painted area of object material fills the
FOV of the thermometer.
Aim the thermometer at another spot on the target - Area “B” in
Figure C-1.
Adjust the emissivity of the thermometer until the temperature
reading equals the temperature found in Step 2.

Use this method where practical to measure objects at
temperatures above 500°F (260°C).
Drill a 1.5" (35 mm) diameter hole in a sample of the object
material to a depth of 5" (127 mm). This hole closely resembles a
blackbody (refer to Appendix A).
