Non-contact Infrared Digital Thermometer GM400 (Batteries Included)

This is the LASERGRIP GM400 FC non-contact infrared thermometer (thermometer gun).
This is a tool for measuring the surface temperature of objects and is not a thermometer. Do not use it to measure human body temperature as the accuracy differs.
Basic Usage
To Measure: Pull the trigger to turn on the power and activate the laser. Keep the laser pointed at the object you want to measure, and the temperature will be displayed in real-time (SCAN mode).
To Hold Value: Release the trigger, and the last measured temperature will be fixed on the screen (HOLD).
To Turn Off: The power will automatically turn off after a few seconds (approx. 7-15 seconds) of inactivity.

Function of Each Button
You can change settings using the buttons below the LCD screen.
°C/°F Button: Switches between Celsius (°C) and Fahrenheit (°F) display.
Laser Button: Turns the aiming laser on and off.
Backlight Button: Turns on the light so you can see the screen in dark places.

Tips for Accurate Measurement
Pay Attention to Distance: If you are too far from the object you are measuring, surrounding temperatures will mix in, making accurate measurement difficult. A distance of about 36cm is generally recommended.
Difficult Materials: Shiny metals and glass tend to reflect infrared rays, which may result in a lower temperature reading than the actual temperature. In such cases, applying black masking tape or similar to the surface before measuring will provide more accurate results.
