Penetration thermometers are designed specifically for measurement in liquids and viscoplastic media (meat, fish, dough, etc.). For instance, insertion into yoghurt or milk packaging enables the real core temperature of the product to be determined.
This measuring method is very accurate and reliable for certainty of product temperature.
However, the disadvantage is that a product that has been "pierced" can no longer be sold and therefore must either be processed as quickly as possible, or disposed of.

For measurements with a probe thermometer, the temperature probe is inserted directly into the measurement object. The measurement is finished when the so-called t99 time is reached. That is the time which a probe needs to achieve 99% of its final value. The 90% value is achieved considerably sooner, but it takes just as long again to get from the 90% value to the 99% value. All data concerning the acclimatization time of temperature probes in Testo documents refer to the t99 time.
An error that frequently occurs with temperature measurement is that the probe and the measured object have different temperatures. This means either heat is supplied to the measurement object (probe warmer) or taken from it (probe colder) – and therefore energy as well. And the real temperature is no longer measured due to the energy extraction. However, this measurement error can be minimized by choosing a penetration depth of 10 to 15 times the diameter of the probe. For immersion measurements in liquids, the measurement error can also be reduced by the liquid being constantly kept in motion. This measurement error also occurs when using a food probe to measure foods, especially frozen goods, but it can be avoided through a sufficient penetration depth.
Reliable and fast temperature measurement with an penetration thermometer is of particular importance in the food sector. However, in addition to core temperature measurements, non-contact measurement of surface temperatures are required The testo 104-IR BT combined instrument was specifically developed for this. It combines penetration and infrared thermometers in a compact format.

In contrast to penetration thermometers, thermal imagers do not measure temperatures inside a measurement object, but on its surface. To do this, they measure the thermal radiation emanating from the object and convert it into a thermal image. Thermal anomalies can then be very quickly and clearly identified on this image. Thermal imagers are often used in preventive maintenance or in the construction industry to detect weak spots on systems or buildings
For many applications, it is not enough to only measure temperatures. The temperature must be recorded as a time progression, especially in storage of sensitive goods, such as food. Temperature data loggers are suitable for this. Unobtrusively attached to the wall, they measure and document temperatures and other ambient conditions at adjustable intervals.
With temperature measuring strips and an appropriate surface temperature meter, you can quickly record the surface temperature of a measurement object. Ideal if direct contact with the object does not present a problem.
Infrared thermometers are perfect for non-contact measurement of temperatures from a distance. The Smart Probes are available for a wide variety of measuring tasks. The main attraction for you: they are operated entirely via your smartphone/tablet and the testo Smart App.
