10:1 Mini IR Thermometer
User Manual
Introduction
Congratulations on your purchase of the IRT225 10:1 infrared thermometer The IRT225 can quickly and accurately determine the surface temperature by measuring the infrared energy radiated from the target surface. It is suitable for non-contact surface temperature measurements.
Safety
Warning:
LASER RADIATION DO NOT STARE INTO THE BEAM
OUTPUT < 1mW COMPLIES WITH EN60825-1:2014
To avoid eyes or personal injury, please read the following safety instructions before using the thermometer:
-
Please do not irradiate people or animals with laser directly or indirectly.
-
Please do not look at the laser directly or through other optical tools (telescope, microscope, etc).
-
If the battery symbol on the LCD display is flashing, replace batteries immediately to avoid inaccurate measurements before using the thermometer.
-
Inspect the case before using the thermometer. Do not use the thermometer if it appears damaged. Look for cracks or missing plastic.
-
Please refer to the emissivity information for the actual temperature.
Reflective objects can cause the actual temperature value to be higher than the measured temperature value. When measuring these objects, please be aware not to touch high-temperature surfaces. -
Do not use the thermometer in explosive gas, steam, or humid environment.
-
To ensure measurement accuracy, place the thermometer in the current environment for more than 30 minutes before using it.
-
Avoid keeping the thermometer near high-temperature objects for a long time.

LCD DESCRIPTION
Operation
Viewing the Last Measured Value
In the off state, short press the trigger to turn on the thermometer, it will
display the last measurement data that was held before the last shutdown.
Temperature Measurement
Aim the thermometer at the target, then pull and hold the trigger, the laser
indicator on the LCD display shows that the laser is turned on and points to
the target, the measured temperature value will be displayed on the LCD, and
the maximum or minimum temperature of the target area can be measured by
scanning up, down, left and right according to the laser spot indication.
Note: The measurement distance must be determined by the size of the measured
target according to the “distance to spot size ratio (D:S)” and “field of
view”.
Hold
After the trigger is released, the last measured value and the HOLD icon will
remain on the LCD display. If there is no operation for 8 seconds, the
thermometer will automatically shut down and save the last measured value.
Unit Conversion
In the power-on state, open the battery cover and short press the °C/°F button
to switch the temperature unit to Celsius (°C) or Fahrenheit (°F).
Distance to Spot Size Ratio (D:S)
As the distance (D) from the target being measured increases, the spot size
(S) on the measured area becomes larger. The relationship between the distance
and the spot diameter is as shown in the figure below.
The spot diameter represents 90% of the energy in the circle. The maximum D:S (10:1) will be obtained when the thermometer is 400mm (16’’) from the target resulting in a spot diameter of 40mm (1.6’’).
Field of View
Make sure that the measured target is larger than the spot diameter. The
smaller the target is, the closer the test distance should be (please refer to
D:S for the spot diameter at different distances). To obtain the best
measurement result, it is recommended that the target being measured is 2.5
times larger than the spot diameter.
Troubleshooting
| Symptom | Problem | Action |
|---|
OL appears
when measuring| The measured value is greater than the maximum range| Stop
measuring
-OL appears when measuring| The measured value is less than the minimum range| Stop measuring
Err appears
when booting| Exceeding the minimum or maximum operating ambient temperature|
Place the thermometer in a 0°C-50°C (32°F-122°F) environment, and it can be
recovered after 30 minutes
Battery indicator flashes| Low battery| Replace batteries
Laser fails to work / weak laser| Low battery| Replace batteries
The measurement is inaccurate| Low battery, emissivity mismatching, the
measured distance is too far, measured target diameter is less than 20mm,
etc.| Please refer to the instructions for the field of view, D:S, etc.
Maintenance
Cleaning and storage
- The meter should be wiped with a damp cloth and mild detergent when necessary. Do not use solvents or abrasives.
- Store the meter in an area with moderate temperature and humidity.
Battery Replacement
Please install or replace the batteries (AAA (LR03) 2*1.5V) as shown on the
right.
