Over 35 Years – Precision in Temperature

In November 1986, the Klasmeier company was founded as a sales company for temperature calibration equipment under the brand name ISOTECH. Since then, the scope of tasks has continuously evolved. The planning and commissioning of calibration facilities, as well as the high-precision representation and recording of the physical parameter of temperature, were added.

Since 1997, we have operated our own accredited temperature calibration laboratory. Typically, in such laboratories, temperature recording systems to be calibrated are compared in thermostats with calibrated reference sensors. The documented difference is a measure of the calibration result. We take our own approach here by using defining fixed points of the International Temperature Scale of 1990 (ITS-90) to perform high-precision calibrations. In the temperature range from -189°C (triple point of high-purity argon) to 962°C (freezing point of high-purity silver), these defining fixed points can be represented and measured with an accuracy of up to 1/1000°C (1 mK).

Our fixed points and measuring equipment are linked to the German national standards of the PTB (Physikalisch Technische Bundesanstalt) and to the English calibration service UKAS as well as the DAkkS. Thus, all measurements and calibrations are traceable to national and international standards. Additionally, we can perform traceable factory calibrations in the temperature range from -200°C to 1300°C.

At the beginning of 2007, we moved into new premises in Flemingstraße in Fulda. This tripled the spatial capacity of our calibration laboratory.
