Temperature measuring instruments

Thermometers to meet every challenge

There is surely hardly any more important measurement parameter than temperature. We are confronted with it on a daily basis and most people have individual preferences as to what exactly the right temperature is in specific situations. And this is where the greatest problem actually lies: people only feel temperature.

However, temperature measuring instruments have to be used for objective and comparable results. Depending on the specific application, you will find different thermometers, temperature meters or digital thermometers for that purpose at Testo.

A Testo temperature meter offers you the following

  • Robust construction, even for tough practical use

  • High-precision sensor technology for reliable and accurate measurement results

  • Comprehensive selection of probes for your temperature meter - customized products too

  • Calibration and servicing from one provider

Temperature measuring instruments in use

The fields of application for temperature meters, digital thermometers and temperature measuring instruments are very varied. Here are just the most important ones:

  • Spot checking of food

  • Temperature monitoring of food transportation

  • Measuring the temperature in the centre of flue gas flow in chimneys/flue gas ducts

  • Measurement of different air temperatures

  • Surface measurement for checking the pre-heating temperature when welding

  • Immersion measurement in chemical solutions for maintaining temperatures during etching processes

  • Surface temperature measurement on bearings and gear mechanisms in mechanical engineering
