General Description
1.1 Introduction
The OS530E/OS520E series Handheld Infrared (IR) Thermometers
provide non-contact temperature measurements up to 4500°F. 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 information at a glance — the custom
backlit dual digital LCD displays both current and minimum,
maximum, average or differential temperatures. This versatile
instrument provides:
• Measurable target distances from 5 inches to approximately 100
feet
• Emissivity adjustable from 0.1 to 1.00 in 0.01 steps provides ease
of use when measuring a variety of surfaces.
• Built-in Laser sighting in Circle & Dot configurations.
• Thermocouple input available.
• Distance Measurement available, either field mountable or built-
in.
• Digital/Video Camera Option available
• An electronic trigger lock feature set via the keypad allows
continuous temperature measurement up to 10 times per second.
• Audible and visual alarms. The high and low alarm points
are set via the keypad.
• 1 mV per degree (°F or °C) analog output, which allows
interfacing with data acquisition equipment (including
chart recorders, dataloggers and computers). OS524E provides 0.5
mV/Deg.
• Last temperature recall (Hold).
• Backlit display useful in low ambient light conditions.
• Powers from 4 AA size batteries or an ac adapter.
• RS232 serial communication to a PC or printer. This allows
downloading data for further analysis.
• Ambient target temperature compensation. This provides more
accuracy for measuring low emissivity targets.
• Record up to 800 temperature data points. Review the recorded
data on the thermometer LCD, as well as downloading the data
to a PC.

2.3.4 Using the Distance Function
CAUTION
• There should be a clean, open line of sight from the distance
LCK
device to the target, otherwise an erroneous reading will result.
• For accurate distance measurement readings, the surface
must be hard, flat, and reflective to ultrasonic pulse.
• Distance measurement can not be taken through glass, or
off of soft and padded surfaces, or through smoke or fog.
• The distance measurement unit must be held perpendicular
to the target surface.
• The distance measurement unit is designed for indoor use only.
• Accuracy of the distance measurement unit will vary
depending on environmental conditions.
• Do not aim the distance measurement unit at a person.
The thermometer provides distance measurement as an option. This function
is either built-in or field mountable. The field mountable version (HH-DM)
mounts on top of the thermometer and is a stand-alone device. It operates

Laser Sighting
3.2 Description
The Laser Sighting is built into the thermometer. It provides a visual
indication of the field of view of the thermometer. Aiming at distant
targets (up to 40 feet) becomes much easier by using the Laser
Sighting. It is offered in two different models, laser dot, and laser
dot/circle switchable. The Laser can be set to either flashing or
continous.
OS53x-CF and OS523-3 — Thermometer with built-in Laser Dot
All other models — Thermometer with built-in Laser Dot/Circle Switchable
Figures 3-1 and 3-2 show the side and front view of the thermometer with the
built-in laser sighting.

3.3 Operating the Laser Sighting
1. Set the laser power switch to the ON position as shown in
Figure 3-2.
2. Aim at the target and pull the trigger.
3. The laser beam and the red power indicator LED will turn on.
Refer to Figure 3-1 and Figure 3-2.
The laser beam will stay on as long as the trigger is pulled.
LOCK
If the trigger is locked (the
key is previously pressed) or
released, the laser beam will turn off. In order to turn on the
Laser Sighting, pull the trigger again.
4. Depending on the model, the laser dot/circle switch allows the user
to switch between laser dot and laser circle. The laser dot provides
visibility at longer distances.
Figure 3-3 shows the two different laser configurations. The laser
Dot indicates the center of the field of view of the thermometer.
The laser Circle indicates the perimeter of the thermometer’s field
of view.
The visibility of the laser beam depends on the ambient light levels.

Laser Sighting
NOTE
The Laser Sighting turns on only when used with the
thermometer. The module does not turn on by itself.
The line of sight of the thermometer does not coincide with that of
the Laser Sighting, as shown in Figure 3-4. The two lines of sight
become less critical when measuring distant targets. For example, at
30 feet from the target and a 3 foot diameter target size, there is a
2.7% offset error with respect to the target size. For close-up targets,
first make sure the target fills the laser circle, then point it with the
center of the beam approximately 1" below the center of the target.
A simple method to make infrared measurements is to scan the laser
beam across the target area vertically and horizontally and recall
measurements of maximum for hot and minimum for cold target
(compared to the background) to obtain the correct temperature.

Sighting Scope
4.1 Sighting Scope
The Sighting scope is an accessory for the thermometer. It provides a visual
indication of the target being measured. Aiming at distant targets (up to 200
feet) becomes much easier by using the Sighting scope.
4.2 Installing and Operating the Sighting Scope
1. If the sighting scope is already installed on the thermometer,
go onto step 5.
2. The sighting scope comes with a pair of mounting clamps
already attached.
3. Slide the pair of mounting clamps over the ”V“ groove of the
thermometer from back to front as shown in FIG 4-1. DO NOT remove
the protective label from the laser sight power contacts.
4. Using the two mounting screws of the clamp, tighten the sighting scope
to the pair of clamps and the thermometer.
5. Look through the sighting scope at an arm’s length. You will see
a crosshair indicating the center of the target being measured.
6. Aim at the target and pull the trigger.
Since the sighting scope mounts on top of the thermometer, the line of
sight of the thermometer does not coincide with that of the sighting
scope, as shown in Fig. 4-1. The distance between the two lines of sight
11
(1 ⁄16") becomes less critical compared to the target size when
measuring distant targets (50 feet and longer).

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
Relative emission from a blackbody versus wavelength.
proportional to the total
energy radiated by the
blackbody at a given
temperature.
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.

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/meter

σ = 5.6703 x 10 watts/meter x K (Stefan’s constant)

T = temperature of object 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.

The distance-to-spot size ratio ( ⁄S) defines the field of view (FOV).

Thus, a ⁄S = 10 gives you approximately a 1 foot spot size at a
distance of 10 feet. For accurate spot size values, refer to the Field of
View diagrams shown in Figures 2-4 through 2-6.

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 OS530 Series Thermometer.
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 260°C
(500°F).
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
‘A’ in 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 ‘B’ as shown in Figure C-1 Make
sure that Area ‘B’ is 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 ‘A’ in 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 ‘B’ in
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 260°C (500°F ).
2. Drill a 35 mm (1.5") diameter hole in a sample of the object
material to a depth of 127 mm (5"). 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 ‘A’ in 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 ‘B’ in Figure C-2).
5. Adjust the emissivity of the thermometer until the temperature
reading equals the temperature found in Step 3.
