General Description  
1.1 Introduction  
The OS550 Series Industrial Infrared (IR) Thermometers provide  
non-contact temperature measurement up to 2500°F (1371°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.  
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" to  
approximately 200'  
• 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 4 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, dataloggers and computers)  
• RS232 serial communication to a PC or printer. This allows  
downloading data for further analysis (OS552, OS553 and  
OS554 only).  
• Ambient target temperature compensation. This provides  
more accuracy for measuring low emissivity targets.  
• Record up to 100 temperature data points. Review the  
recorded data on the thermometer LCD, as well as  
downloading the data to a PC (OS553 and OS554 only).  
• Last temperature recall.  
• Backlit display useful in low ambient light conditions  
• Laser Sighting is optional.

Using the Infrared Thermometer/Transmitter  
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  
keys.  
and  
3. Read the temperature.  
• 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  
dIFappears on the display.  
6. Read the differential temperature from the upper display.  
• Static Surface Scan – Measures the temperature across a static  
surface:  
1. Aim the thermometers sensor head at a starting point.  
2. If necessary, adjust the emissivity.  
3. Slowly move the thermometers sensor head so that the line of  
sight sweeps across the surface. The thermometer measures the

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.

Maintenance  
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  
Department. It is recommended that the Infrared Thermometer be  
sent to the factory once a year for recalibration.

Appendix: How Infrared Thermometry Works  
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.  
Relative emission from a blackbody versus wavelength.  
The area under the curve corresponds to the total ener-  
gy, 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.

Wien’s Displacement Law describes the exact mathematical  
relationship between the temperature of a blackbody and the  
wavelength of the maximum intensity radiation.

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.

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 Xand Yare 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 Xaccurately, Object Ywould  
need to be removed. In order to measure the temperature of Object  
Yaccurately, 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 Ywith a  
thermometer with a smaller FOV.  
Figure A-3. Field of View of a Thermometer/Transmitter  
D
The distance-to-spot size ratio ( ⁄S) defines the field of view (FOV).  
D
Thus, a ⁄  
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 Values  
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  
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 OS551/OS552, OS553 and OS554 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. Measure and record the temperature of the object using a contact  
temperature probe such as a thermocouple or RTD.  
2. Aim the thermometer at the object.  
3. Adjust the emissivity until the temperature reading of the  
thermometer equals the temperature measured in Step 1.  
Method 2  
1. 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.  
2. Measure the temperature of the object material with the  
thermometer. Make sure that the object fills the FOV of the  
thermometer.  
3. Adjust the emissivity until the temperature reading of the  
thermometer equals the known temperature of Step 1.

Appendix: Determining an Unknown Emissivity  
Method 3  
1. Use this method to measure objects at temperatures below  
500°F (260°C).  
2. Place a large piece of masking tape on the object (or at least a  
sample of the object material). Allow time for the masking tape to  
reach the object temperature.  
3. Set the emissivity of the thermometer to 0.95. Use the thermometer  
to measure and record the temperature of the masking tape - Area  
Ain Figure C-1. Make sure that the area of the object covered  
with masking tape fills the FOV of the thermometer.

4. Aim the thermometer at Area Bas shown in Figure C-1 Make  
sure that Area Bis as close as possible to Area A.  
5. Adjust the emissivity of the thermometer until the temperature  
reading equals the temperature found in Step 3.

Appendix: Determining an Unknown Emissivity  
Method 4  
1. Paint a sample of the object material with flat black lacquer paint.  
2. Set the emissivity to 0.97 and measure and record the temperature  
of the painted portion of the sample material - Area Ain Figure  
C-1. Make sure that the painted area of object material fills the  
FOV of the thermometer.  
3. Aim the thermometer at another spot on the target - Area Bin  
Figure C-1.  
4. Adjust the emissivity of the thermometer until the temperature  
reading equals the temperature found in Step 2.  
Method 5  
1. Use this method where practical to measure objects at  
temperatures above 500°F (260°C).  
2. 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).

3. Set the emissivity to 0.97 and measure and record the temperature  
of the hole in the sample material - Area Ain Figure C-2. Make  
sure that the hole fills the FOV of the thermometer.  
4. Aim the thermometer at another spot on the target as close as  
possible to Area A(Area Bin Figure C-2).  
5. Adjust the emissivity of the thermometer until the temperature  
reading equals the temperature found in Step 3.
