Introduction
Congratulations on your purchase of the Model IR200 IR Thermometer. This thermometer
is intended for scanning groups of individuals or monitoring an individual for elevated
temperatures. It is not a substitute for a clinical thermometer. Always use a clinical
thermometer when high accuracy body temperature measurements are required.
Considerations and Warnings
Read all instructions before using this product.
For the most accurate results, make reading with an ambient (room) temperature of
73 to 82°F (23 to 27°C)
Make sure the skin is dry and that no hair interferes with the measurement.
Do not immerse the meter in water.
Avoid touching and/or scratching the infrared sensor lens.
Always use a clinical thermometer to verify any abnormal temperature
measurements.
Clean the lens area by gently blowing with compressed air and use a damp swab
to wipe the lens. Do not use any solvents to clean the lens.
Measurement Notes
1. If the meter has been stored in a cold or hot environment, allow it at least 20 minutes
to acclimate to room temperature before making measurements.
2. To prevent transmission of disease, avoid direct contact with the skin.
3. After heavy exercise always wait at least 10 minutes before taking forehead
temperature readings.
Warranty
EXTECH INSTRUMENTS CORPORATION (a FLIR company) warrants this instrument to be free of defects in
parts and workmanship for one year from date of shipment (a six month limited warranty applies on sensors

Operating Instructions
Body Temperature Measurements
1. Set the Body-Surface- switch for “Body” for accurate measurements in the range of
.86.0 to 109°F (30 to 43°C).
2. Hold the meter by its handle and point it toward the surface to be measured.
Measurement distance should be 2 to 6” (5 to 15cm).
3. Press the trigger to turn the meter on and take a temperature reading. The
temperature reading appears in the large display and the logged data number and
value appear in the smaller display.
4. Release the Trigger and the reading will hold for approximately 7 seconds after which
the meter will automatically shut off. Trigger presses can occur up to a rate of one a
second to quickly log samples.
5. If the temperature goes above 109°F or 43°C, Hi will appear in the display.
If the temperature goes below 86°F or 30°C, Lo will appear in the display.
Body Temperature Mode settings
1. With the meter OFF, press the MODE button once to set the C/F temperature units.
The temperature units will flash. Press the ▲or ▼buttons to change the units.
2. Press the MODE button a second time to set the alarm temperature limit. Press the ▲
or ▼buttons to change the value.
3. Press the MODE button a third time to enter the long term calibration drift correction
mode. On entering the mode, the previous temperature correction factor will appear
on the display. To make a correction, measure a known, fixed temperature source.
Enter the correction mode and press the ▲or ▼buttons to change the correction
value and minimize the difference in readings. Repeat and adjust the correction value
as needed until the measurement on the IR200 matches the known temperature.
4. Press the MODE button a fourth time to set the alarm buzzer status. Press the ▲or
▼buttons to switch from ON to OFF.
Surface Temperature Measurements
1. Set the Body-Surface- switch for “Surface” for wide range surface measurements of
most materials.
2. Hold the meter by its handle and point it toward the surface to be measured.
3. Press the trigger to turn the meter on and take a temperature reading. The
temperature reading appears in the large display and the logged data number and
value appear in the smaller display.
4. Release the Trigger and the reading will hold for approximately 7 seconds after which
the meter will automatically shut off. Trigger presses can occur up to a rate of one a
second to quickly log samples.
5. If the temperature goes above 140°F or 60°C, “Hi” will appear in the display.
If the temperature goes below 32°F or 0°C, “Lo” will appear in the display.

SurfaceTemperature Mode settings
1. With the meter OFF, press the MODE button once to set the C/F temperature units.
The temperature units will flash. Press the ▲or ▼buttons to change the units.
2. Press the MODE button a second time to set the alarm temperature limit. Press the
▲or ▼buttons to change the value.
3. Press the MODE button a third time to set the alarm buzzer status. Press the ▲or
▼buttons to switch from ON to OFF.
Data memory
To review the logged data points, press both the ▲and ▼buttons while the unit is OFF.
Use the ▲or ▼buttons to scroll through the memory locations. To clear logged data,
select the “0” memory location and press the MODE button. The unit will beep twice to
indicate memory has been cleared.
Field of View
The meter’s field of view is 8:1. For example, if the meter is 8” (20cm) from the target
(spot), the diameter of the target must greater than 1” (2.5cm). Other distances are
shown in the field of view diagram. Measurements should normally be made as close as
possible to the device under test. The meter can measure from greater distances but the
measurement may be affected by external sources of light. In addition, the spot size
may be so large that it encompasses surface areas not intended to be measured.
Battery Replacement
When the low battery symbol appears on the display, replace the meter’s battery. The
battery compartment is located on the bottom of the handle. Open the compartment by
removing one screw and sliding the cover off. Replace the (2) “AA” batteries and close the
battery compartment cover.

IR Measurement Notes
1. The object under test should be larger than the spot (target) size calculated by the field
of view diagram (printed on the side of the meter and in this guide).
2. Before measuring, be sure to clean surfaces that are covered with frost, oil, grime, etc.
3. If an object's surface is highly reflective, apply masking tape or flat black paint to the
surface before measuring. Allow time for the paint or tape to adjust to the temperature
of the surface it is covering.
4. Measurements through transparent surfaces such as glass may not be accurate.
5. Steam, dust, smoke, etc. can obscure measurements.
6. The meter automatically compensates for deviations in ambient temperature. However,
it can take up to 30 minutes for the meter to adjust to extremely wide changes.
