Temperature is a very important measurement parameter in industry, science and research. A high degree of precision is essential, which requires the use of infrared thermometers (also known as pyrometers) or thermal imagers. We present both products in detail here.
Pyrometers and thermal imagers: Measure surface temperature quickly and without contact
Pyrometers: For single-point temperature measurements H3>
The pyrometer offers the following features, among others:
- Fast, non-contact measurement of surface temperatures
- Easy measurement in places that are difficult to access
- Precision technology for the most stringent requirements
- Reliable temperature measuring instrument
Thermal imagers: Visualize temperatures over large surfaces H3>
A thermal imager gives you not just a single temperature measurement value – but over 76,800 of them, such as in the case of the thermal imager testo 872.
Thermal imagers offer you these advantages, among others:
- Complete overview, for example in order to identify hot spots which could be overlooked with a pyrometer
- Fast and easy visualization of temperature differences
- Measurement of small and large objects with just one measuring instrument.

The pyrometer is considered to be an optimally usable and versatile temperature measuring instrument. The parameters emissivity and distance or measurement spot must be taken into consideration. To ensure safe use of the pyrometers, Testo stores an emissivity table in each instrument, which can be used to quickly set the emissivities. In addition, the distance to the measuring object plays a role: to ensure accuracy, the person measuring must be far enough away that the entire extent of the measurement spot is lying on the measuring object. The further away you are from the measuring object, the larger the measurement spot will be.
It is also important to choose the right pyrometer. Here, you should ask yourself in advance what you need this type of temperature measuring instrument for. Is it sufficient to measure the surface temperature or is it also necessary to determine the core temperature? If it’s a case of the latter, then a combined pyrometer/penetration thermometer is the appropriate choice. It is also important as to whether the data is to be transferred to a mobile device. For example, Smart Probes offer the option of transmitting the measurement data from the respective measuring instrument to the Testo Smart Probes App – either as a diagram or in tabular form.
The following aspects are also relevant when it comes to measuring temperature with a pyrometer:
- Measurement spot (measuring range depends on the distance to the measuring object)
- Ambient temperature
- Surface to be measured - emissivity
- Additional contact measurement necessary
testo 805i – infrared thermometer operated by smartphone
For the non-contact measurement of wall, fuse and component temperatures of air conditioning systems.
Temperature measuring strips are not used in all areas of everyday life or of trade and industry. Application of the strips is quite simple: They are simply stuck onto the object to be measured and they change their colour depending on the influence of the surface temperature.
They are available in various designs and are suitable for a wide range of applications. Nevertheless, pyrometers, which provide exact measurement results with non-contact temperature measurement thanks to their innovative technology, are much more widely used.

Measuring food temperature correctly with infrared thermometers.
Is there really such a thing as a temperature measuring instrument that carries out accurate measurements and also offers the option of transferring the data to a smartphone? There certainly is, because Testo has been offering this kind of measuring technology for a long time. Various thermometers and measuring instruments for other values can be used in the form of a Smart Probes kit.
The measured values are transferred to the app on the smartphone so that the data can be viewed and evaluated at any time. Thermal imagers are also used as pyrometers and detect cold bridges, just like they examine mechanical systems and electrical switch cabinets for heat sources.
