1. Introduction
This infrared thermometer is designed for measuring the surface temperature of objects without contact. It is ideal for various hot, hazardous, or hard-to-reach objects, allowing for safe and quick temperature readings.
2. Safety Warnings & Cautions
2.1. Warnings
To avoid potential harm or damage, please observe the following:
- Before use, inspect the plastic housing. Do not use if damaged.
- Do not point the laser directly at eyes or indirectly off reflective surfaces.
- Do not use this unit in environments with explosive gas, steam, or dust.
2.2. Cautions
To prevent damage to the unit or the target, protect it from the following situations:
- Electromagnetic fields (EMF) from arc welders or induction heaters.
- Thermal shock caused by large or abrupt ambient temperature changes. Allow 30 minutes for the unit to stabilize before use.
- Do not leave the unit on or near objects of high temperature.
3. Setup
3.1. Battery Installation
- Locate the battery compartment at the bottom of the handle.
- Open the battery compartment. You may need a screwdriver to rotate the switch knob to unlock it.
- Insert two 1.5V AAA batteries, ensuring correct polarity.
- Close the battery compartment securely.
4. Operating Instructions
4.1. Component Overview
4.2. Distance to Spot Size (D:S Ratio)
When taking measurements, pay attention to the Distance to Spot (D:S) ratio. As the distance (D) from the thermometer to the target surface increases, the spot diameter (S) on the target surface becomes larger. This model has a D:S ratio of approximately 12:1. For accurate measurements, ensure the target is at least twice as large as the measuring area. It is recommended not to exceed 1 meter for testing.
4.3. Measurement Modes
- Single Measurement: Pull and release the trigger. The laser point will activate to help aim at the target. The temperature will be displayed on the LCD. The 'HOLD' symbol will appear, indicating the current temperature value is held.
- Continuous Measurement: Pull and hold the trigger. Slowly move the thermometer across the target area. The thermometer will continuously scan and display the temperature on the LCD. The 'SCAN' symbol will appear, and the maximum temperature value during continuous measurement will also be displayed.
4.4. Display Indications and Controls
- HOLD (A): Appears when a single measurement is taken and the temperature value is held.
- SCAN (B): Appears during continuous measurement.
- Laser Point (C): Press button (2) to turn the laser on/off. The laser is for aiming only.
- Backlight (D): Press button (4) to turn the LCD backlight on/off.
- Power (E): Battery capacity indicator.
- Temperature Unit (F): Press button (3) to switch between Celsius (°C) and Fahrenheit (°F).
- Temperature Value (G): Displays the current temperature.
- Emissivity Symbol (H): Indicates emissivity setting.
- Max Symbol (I): Indicates maximum temperature.
- Max Temperature Value or Emissivity (J): Displays max temperature or emissivity setting.
4.5. Emissivity Adjustment (T600A Model Only)
The T600A model features adjustable emissivity. To adjust:
- Long press button (3). The preset emissivity of 0.95 will be displayed at position (J).
- Press button (2) or (4) to increase or decrease the emissivity value.
- Press button (3) again to save the new emissivity setting.
Different materials have different emissivities. For more accurate readings, adjust the emissivity according to the material being measured. Refer to the Emissivity Reference Table below.
5. Maintenance
5.1. Lens Cleaning
To clean the lens, first use compressed air to blow away any debris. Then, use a camel hair brush to gently wipe away residual small debris. Finally, wipe the surface carefully with a wet cotton cloth.
5.2. Shell Cleaning
Use a sponge or soft cloth with soap and water to clean the thermometer's shell.
6. Troubleshooting
- No Power: Check battery installation and ensure batteries are not depleted. Replace with fresh AAA batteries if necessary.
- Inaccurate Readings: Ensure the D:S ratio is appropriate for the measurement distance. For T600A, verify the emissivity setting matches the material being measured. Allow 30 minutes for the unit to stabilize if moved from a significantly different temperature environment.
- Laser Not Working: Check if the laser point is enabled via button (2).
- Display Not Clear: Activate the backlight using button (4).

8. User Tips
- For best accuracy, especially with the T600A model, always ensure the emissivity setting matches the material you are measuring. Refer to the emissivity table for common materials.
- Keep the lens clean to prevent inaccurate readings. Dust or smudges can significantly affect performance.
- Remember that infrared thermometers measure surface temperature. They are not designed for internal body temperature measurement of humans or animals.
