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
Thermometers operated by smartphone


Compact measuring instruments for your smartphone
Our all-rounders for all important measuring tasks. Members of the Smart Probes family are not just temperature measuring instruments. These innovations also include pressure and flow meters, all fully operated via the testo Smart Probes App.
The testo Smart Probes VAC kit enables you to measure temperature, speed and air humidity, as well as to calculate volume flows. Ideal for air conditioning and ventilation systems.
Tips and tricks for temperature measurement and monitoring

A temperature meter in itself means you have already taken the first step. However, you need to bear a few things in mind for really efficient and precise temperature measurement.

Record temperatures
There are applications where a temperature meter is not enough. For instance, when it is a case of monitoring temperatures over the long term and reliably recording the readings. This is where temperature data loggers are used. The small aids are ideally suited for temperature monitoring, making work a little bit easier every day for quality managers and facility managers all over the world.
Transmitters
When you need to integrate temperature readings seamlessly into automated building services, then it is temperature transmitters that are required. First of all, they measure the temperature, just like a temperature meter – however, they then convert the measuring values into a standardized electrical signal which can be further processed to control specific procedures.
Measure surface temperatures
In the broad spectrum of temperature measurement, particularly high importance is attached to surface temperature measurement. Because it is not just in industry, trade or facility management that a surface temperature measuring instrument is used. The food industry is also – and above all – the sector where this measurement method is one of the most common. In the end, spot checks on the quality of food can be carried out quickly and reliably using surface temperature measurement. And precise measurement of the surface temperature often makes laborious measurement of the core temperature superfluous.
