Infrared thermometer

With infrared measurement (IR measurement), the temperature is measured without contact on surfaces and also at a distance.

High-precision, safe and robust

Temperature is surely the most frequently measured physical quantity. There are various options available for measuring temperature using infrared light. In addition to traditional thermometers, pyrometers (also known as laser thermometers or IR thermometers) are also proven instruments for measuring temperature.

An infrared thermometer from Testo offers you the following

  • An instrument for the fast, non-contact measurement of the surface temperature.

  • Easy temperature measurement, even with dynamic processes or in locations that are difficult to access.

  • Reliable temperature measurement with cost-effective technology.

Correct measurement made easy: pro tips for using laser thermometers

A temperature measuring instrument such as the infrared thermometer is precise, safe and easy to operate. With a couple of useful tips and tricks, you can achieve even better measurement results:

Background information on infrared measurement

Although the IR thermometer is an ideal instrument for measuring temperature, certain aspects also have to be considered:

  • Emissivity of the measurement object. Testo laser thermometers have a stored emissivity table.

  • In cool surroundings, this thermometer requires a certain acclimatisation time.

  • Do not stand too far away from the measurement object, otherwise the measurement will be inaccurate.

The laser thermometer for the most stringent demands

testo 835-H1 with moisture measurement

Over 60 years ago, Testo launched its very first product – an electronic thermometer. This experience in developing innovative temperature measuring instruments can now be seen in the testo 835-H1 – the ultimate tool for non-contact temperature measurement.

Your advantages with the testo 835-H1

  • 4-Point-Laser: shows the exact measuring zone, effectively preventing wrong measurements

  • 50:1 optics that provide you with excellent surface temperature measurements even over greater distances (distance 5 m = 10 cm measurement spot)

  • Adjustable degree of emission for measuring a wide variety of different surfaces

  • Connectivity for temperature sensors: for additional contact measurements for materials with low degree of emission possible – simply connect your optionally available temperature sensor

It also works without infrared:
