Introduction
Congratulations on your purchase of the Model 42500 IR Thermometer. This thermometer makes non-
contact (infrared) temperature measurements at the touch of a button. The built-in laser pointer
increases target accuracy while the backlit LCD and handy push-buttons combine for convenient,
ergonomic operation. This device is shipped fully tested and calibrated and, with proper use, will
provide years of reliable service. Please visit our website (www.extech.com) to check for the latest
version of this User Guide, Product Updates, and Customer Support.
Safety
 Use extreme caution when the laser pointer beam is on
 Do not point the beam toward anyone's eye or allow the beam to
strike the eye from a reflective surface
 Do not use the laser near explosive gases or in other potentially
explosive areas

Operating Instructions
1. Hold the meter by its Handle Grip and point it toward the surface to be measured. Read the
Field of View section below for distance to target ratio information.
2. Pull and hold the Trigger to turn the meter on and begin testing. The display will light if the
battery is good. Replace the battery if the display does not light.
3. While continuing to pull the Trigger:
a. Push the Laser button to switch the laser pointer ON. When the laser is on, the laser
icon will appear on the LCD over the temperature reading. Aim the red beam
approximately a half inch below the point of test (pressing the Laser button again turns the
laser off).
b. Select the temperature units using the
oC / oF button.
c. Push the backlight button to switch ON the LCD backlighting function.
4. Release the Trigger; the reading will hold for approximately 6 seconds, after which the meter will
automatically shut off.
5. The meter defaults to the programmed conditions in use when the meter was last switched off.
For example, if the laser is set to ON and the temperature units are set to
oF at the time the unit
is switched OFF, the unit will switch ON and use the same settings.
Over-range Indicator
If the temperature measurement exceeds 500°F (260°C), the thermometer will display dashes in
place of a temperature reading.
Field of View
The meter’s field of view is 6:1. For example, if the meter is 30cm (approx.12”) from the target
(spot), the diameter of the target must be at least 5cm (approx. 2”). Other distances are shown
below in the field of view diagram.
Note that measurements should normally be made closer than 60cm (approx. 2’) from the target.
The meter can measure from further 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.
