Product specification

With the infrared thermometer from TFA, you can quickly and easily measure the temperature of surfaces without touching them. Just aim at the object to be measured, press the button and you'll get the result in a matter of seconds. The built-in laser sight makes it easy for you to find your target. The current temperature is shown on the illuminated display.

Infrared thermometers can be used in many different ways. You can use them to check air-conditioning and heating systems, look for cold bridges and faulty relays or test the brake system in a car. At home, you can check the temperature of baby food, drinks, bath water, frying fat, jam or chocolate mass.

The device is HACCP-compliant and this hygienic, non-contact temperature measurement is ideal for professional use in the food sector.

Non-contact measurement – made possible by its 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 shown on the display.
