The HVAC measuring instrument has a measuring range of -50 ... +500 °C and covers a wide temperature range. With an accuracy of ±2 % ±2 °C at 20 ... 500 °C, the HVAC measuring device is a very precise measuring instrument. For better orientation of the measuring spot, a laser pointer is built into the HVAC measuring device. This laser on the HVAC measuring device has an output power of <1 mW. The emission value of the HVAC measuring device is fixed at 0.95.

The HVAC measuring device is used, for example, for surface temperature testing of electric motors, combustion engines or heat sinks. Thanks to its compact design, the HVAC measuring device is handy and can be easily stowed away. 

To switch on the HVAC measuring device, the measuring button must be pressed. The measurement is then immediately taken by the HVAC measuring device. When the button is released, the last value remains on the display of the HVAC measuring device until a new measurement is carried out. Optionally, the HVAC meter can be equipped with an ISO calibration certificate.
