We ThermoExperts° stand for precision - and not just in production.

We manufacture all our sheathed thermocouples in accordance with DIN EN 60584, but demanding applications for temperature measurement or generation and complex heating solutions require particular precision in special cases. No problem! We are happy to give our mineral-insulated sheathed thermocouples, heating conductors and heating applications the necessary finishing touches:

Precision at the highest level

Helium leak test Mineral-insulated sheathed heating conductor Services from Thermo Expert

Helium leak test

The helium leak test is primarily used for components that are used for an application or in a production process that takes place in a vacuum or ultra-high vacuum (UHV). In order to avoid pressure loss in the application, we test welds and screw connections on our sheath thermocouples or heating applications in advance. On request, we can also supply vacuum-compatible products, including a test report, which are ready for immediate use on site.

X-ray services Mineral-insulated sheathed thermocouples


X-rays are a non-destructive and highly precise method for examining and checking the condition and tightness of the material. The imaging process can be used to determine faults in installed sheathed thermocouples or heatsealing bands. It can also be used, for example, to determine the exact measuring point so that the sheathed thermocouple can be installed precisely. On request, we are happy to supply our thermocouples with X-ray images including dimensions and labeling.

Calibration ThermoExpert services Sheathed thermocouple Heating solution


If the accuracy of the measurement is important, we calibrate our mineral-insulated sheathed thermocouples using the fixed point or comparison method. This allows deviations within the standard to be determined precisely. Especially when several measuring points are present in applications, it can be important to know the exact deviation of the individual thermocouples. Accordingly, we offer factory calibration as well as DAkkS calibration.
