The inclusion of an adjustable emissivity setting allows for precise readings across various surface types, from metals to non-metallic materials. The vibrant EBTN color display ensures excellent visibility in all lighting conditions, while the integrated data logging function allows for the storage of up to 99 measurement results complete with time and date stamps. Its robust construction, including a 1-meter drop resistance, makes it a durable companion for daily professional use.
Suitable for
Industrial equipment maintenance and monitoring
Electrical panel and circuit diagnostics
HVAC system inspection and troubleshooting
Automotive engine and component temperature checks
Food safety and storage temperature monitoring
When it may not be suitable
This device is designed for surface temperature measurement and cannot measure the internal temperature of objects or fluids. It is not intended for medical use, such as measuring human body temperature, and may provide inaccurate results if used on highly reflective or transparent surfaces without proper emissivity calibration.

How to use
To begin, insert the 9V battery into the handle compartment. Power on the device and select the desired emissivity setting based on the material of the surface you are measuring. Point the ring laser at the target area and pull the trigger to initiate the measurement. The result will appear instantly on the EBTN display. Use the mode button to cycle through MAX, MIN, AVG, or DIFF functions as needed. To save a reading, utilize the built-in memory function to log the data for later review.
What to consider before purchase
Ensure the 30:1 distance-to-spot ratio meets your specific measurement distance requirements.
Verify that the adjustable emissivity range covers the materials you intend to measure.
Consider if the 99-entry memory capacity is sufficient for your data logging needs.
Check if the operating temperature range is suitable for your specific work environment.
Usage recommendations
For the most accurate results, ensure the target surface is clean and free of dust or debris. When measuring highly reflective surfaces, apply a piece of matte tape or paint to the area to improve emissivity accuracy. Always maintain a consistent distance from the target to ensure the 30:1 ratio is utilized effectively.
