Why does the temperature need to be monitored?

The temperature of food has a decisive influence on the formation and reproduction of germs and microorganisms and thus also on product quality and consumer health. But how can you ensure that everything is really OK here? With data loggers and thermometers from Testo, you no longer have to worry. The core temperature, storage temperature and thus compliance with the cold chain can be checked at a glance with the measuring devices.

Both the mini data logger for temperature – the Testo 174T – and the thermometers of the Testo 108 product family from the Ehlert range provide you with reliable and precise measurement results with which you can easily comply with the HACCP guidelines.

What is the HACCP concept actually?

EU law obliges all companies that process food and put it on the market to document the control of so-called critical control points within the framework of the food hygiene regulation. This ensures food safety for consumers. This is done with the help of the internal self-control system of the HACCP concept.

Thanks to the Testo data logger, you can keep an eye on the temperature at all times

Do you need a mini data logger for temperature control during the transport of your goods? Then you have come to the right place with the Testo 174T. For example, it can simply be enclosed with the goods in containers or cold rooms and continuously, safely and inconspicuously controls the temperature. A large measuring range and compact design make the Testo 174T a competent helper for temperature recording in every area. The software of the data logger also allows simple and fast programming and data analysis is also an easy game. The integrated NTC sensor allows a high level of accuracy.
