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.

The fields of application for temperature meters, digital thermometers and temperature measuring instruments are very varied. Here are 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
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 App.
testo Smart Probes VAC kit
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.
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.
With your temperature measuring instrument, choose a probe immersion depth of 10 to 15 times the probe diameter. This reduces measurement errors. In addition, it helps the accuracy of the measurement result if you keep the liquid moving during the measurement.
In this case, the probe head is placed vertically onto the surface. Here it is important to ensure that neither the contact surface of the probe head nor the measurement object are uneven, as this can falsify the measurement.
When measuring moving air with a temperature meter, the measurement probe is simply introduced into the environment being measured. Due to its special design, the air probe has a very short response time. The measurement result can be improved by moving the probe through the air at 2 – 3 m/s during the measurement.
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. Ideally suited for temperature monitoring, these little helpers make the work of quality managers and facility managers around the world a little easier every day.
When it comes to seamlessly integrating temperature measurement values into building automation, temperature transmitters are in demand. Similar to a temperature measuring device, they first measure the temperature – but then convert the measured values into a unit electrical signal that can be further processed for the control of certain processes.
In the broad spectrum of temperature measurement, particularly high importance is attached to surface temperature measurement. A surface temperature measuring device is not only used in industry, crafts or facility management. This measuring method is also – and especially – one of the most common in the food industry. 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.
