Description
Overview
GAOTek Non-Contact High Temperature Infrared Thermometer is capable of non-contact temperature measurements at the touch of a button. The built-in laser pointer increases target accuracy while the backlight LCD and handy push-buttons combine for convenient, ergonomic operation. This non-contact infrared thermometer can be used to measure the temperature of the surface of an object which is improper to be measured by the traditional thermometer (such as moving object, the surface with electric current or the objects which are uneasy to be touched).
Key Features
- Non-contact temperature measurements.
- The MODE button options for maximum and minimum temperature value, difference between the maximum and minimum values, and average of the measured values.
- Laser pointer and Backlight button.
- Laser pointers are designed to cross at a distance of 50” (76 cm) with the spot size of 1” diameter at this distance.
- High and Low Alarm feature.
- The temperature units can be set to °F or °C.
- The LOCK feature disables the Auto Power Off feature for the period of use when selected. This feature is useful for long term temperature monitoring and hands free use.
- Over-range temperature indication.
- Battery Replacement symbol indicator on the display.
- The thermometer is capable of storing up to 100 data points.
Applications
- Measurement of the temperature of the moving object
- Measurement of the temperature of the surface with electric current
- Measurement of the temperature of the object which is uneasy to be touched

Operating Instructions
IR Temperature Measurements
- Hold the meter by its handle and point it toward the surface to be measured.
- Pull and hold the trigger to turn the meter on and begin testing. “SCAN” and the temperature reading will appear on the large display. The upper and lower sub-displays will indicate values/settings previously used.
- Release the Trigger and the reading will hold for approximately 7 seconds (“HOLD will appear on the LCD) after which the meter will automatically shut off. The only exception to this is if the LOCK mode is set to ON.
IR Measurement Notes
- The object under test should be larger than the spot (target) size calculated by the field of view diagram.
- Before measuring, be sure to clean surfaces that are covered with frost, oil, grime, etc.
- 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.
- Measurements through transparent surfaces such as glass will not be accurate.
- Steam, dust, smoke, etc. can obscure measurements.
- 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.
- To find a hot spot, aim the meter outside the area of interest then scan across (in an up and down or side to side motion) until the hot spot is located.
The MODE button options
With the trigger pulled (SCAN displayed), press the MODE button to view and scroll through:
MAX: Maximum value measured
MIN: Minimum value measured
DIF: Difference between the Max and Min values
AVG: Average of the measured values
LOG: A memory location is displayed in the small upper display and the value in that location is displayed in the small lower display.
TK: With a Type K thermocouple probe connected to the meter, the probe temperature is displayed in the small lower display.
With the trigger released (HOLD displayed), press the MODE button to scroll through and access the following. The selected item is indicated by a blinking icon.
Laser Pointer and Backlight Button
The laser pointers are designed to cross at a distance of 50″ (76 cm). The spot size at this distance is a 1” diameter and this is the recommended distance to target for most measurements. To turn the lasers on/off:
- Press and Hold the Trigger
- While SCAN is on the display, press and release the backlight/laser
. Either the backlight or laser pointers will change status (On/Off). Repeat this until the desired conditions are set. The laser icon 
will appear in the LCD when the laser function is enabled. - The status of the functions will be stored in memory and will remain as the default “turn-on” condition until changed.
High and Low Alarm Feature
When either programed alarm (high or low) point is reached, the meter will alert the user via an audible beep and a blinking LCD display icon. The alarm limit is set and the feature is enabled/disabled using the MODE button. The setting is stored and memory and will remain as the “turn-on” condition until changed.
Temperature Units
The temperature units can be set to °F or °C. The selection is made using the MODE button.
LOCK Feature
The LOCK feature disables the Auto Power Off feature for the period of use when selected. The feature is useful for long term temperature monitoring and hands-free use. The meter will revert to auto power off if the trigger is pressed during a locked scan. The selection is made using the MODE button.
Over-range Indication
If the temperature measurement exceeds the specified temperature range, the thermometer will display dashes in place of a temperature reading.
Battery Replacement
When the low battery symbol appears on the display, replace the meter’s battery (9 V). The battery compartment is located behind the panel that surrounds the meter’s trigger. Open the compartment, replace the 9 V battery and close the battery compartment cover.
Data Logger
Storing Data: The thermometer is capable of storing up to 100 data points.
Infrared: To store data from an infrared reading
- Pull and Hold the trigger
- Press the MODE button until LOG appears in the lower left corner of the display; a log location number will be displayed. If no temperature has been recorded in the displayed LOG location, 4 dashes will appear in the lower right corner.
- Aim the unit at the target area you want to record, and press the laser/backlight button. The recorded temperature will appear in the lower right corner.
- To select another log location, press the up and down keys.
