Testo 810 Infrared Air Temperature Thermometer
The Testo 810 Infrared Air Temperature Thermometer makes measuring both air and surface values simple and reliable. It works by combining an infrared sensor for surface temperature checks with an NTC sensor for ambient air. Both readings are taken at the same time, giving the user a clear view of temperature differences between the two. This design is especially useful in HVAC checks where quick comparisons are needed.
Precision Surface Measurement
With a 6:1 distance-to-spot ratio, the Testo 810 ensures that users can target surfaces accurately even at short distances. The built-in laser pointer highlights the exact measurement point, removing guesswork when working in tight or awkward spaces. The adjustable emissivity also helps improve accuracy across different surface types. Surface temperatures are displayed within a range of -30°C to 300°C, making it suitable for a wide variety of heating and cooling applications.
Reliable Air Temperature Monitoring
The integrated NTC sensor measures air temperature from -10°C to 50°C, covering typical indoor ranges for property and system checks. The Testo 810 updates values at a fast rate of two measurements per second, so readings remain consistent and easy to track. At the same time, the device displays the differential temperature, helping users to understand heat transfer and identify potential issues more quickly.
The Testo 810 is designed for portability and daily use. It fits into a pocket, includes a protective cap, and provides clear visibility with a backlit LCD screen. The practical functions such as data hold, maximum and minimum values, and differential display further add to its usability. Supplied with batteries and ready for work straight out of the box, this thermometer is a dependable tool for professionals in HVAC and building maintenance.
