The measurement object is simply targeted, the button is pressed, and the result is obtained in seconds. The built-in laser sight makes it easier to find the target. You can monitor HVAC systems, detect thermal bridges and faulty relays, or check the braking system in a car. Contactless measurement is made possible by proven infrared technology. The infrared radiation emitted by any body with a temperature above absolute zero is converted into an electrical signal, evaluated by a processor, and then displayed on the screen.
