Sheathed thermocouples, also known as sheathed thermocouples, are used in various industries and applications where precise temperature measurements are required. This type of thermocouple consists of two different metallic conductors that are connected at one end and open at the other. The open ends are placed at the location where the temperature is to be measured. ThermoExpert° Deutschland GmbH, with its managing directors Heiko Gevert and Andreas Helf, has been a partner to all these branches of industry and research for many years.

We are therefore all the happier that we were able to recruit a new colleague from Syria for our team despite a number of hurdles. There were hurdles both for the new colleague, whose degree in measurement technology was not recognized by the German authorities, and for us, as we also had to deal with a few piles of small print as an employer.

At the end of the day, however, we have gained a valuable, committed new employee for our international team. We tend to see different cultures as an enrichment and as an employer we make it possible to live them.
