Temperature measurement in perfection
Calibration at the very highest level
As a manufacturer of quality temperature sensors, RECKMANN GMBH is backed by decades of experience in the field of temperature measurement technology. We incorporate our outstanding know-how consistently and with determination in the calibration of temperature sensors and temperature measuring instruments.
Our calibration laboratory encompasses a laboratory area of more than 300 m2 with a large number of calibration stations. We master calibration methods such as comparison methods and fixed point calibration to perfection and also do not shy away from comparison with other laboratories.
Our calibration team is characterised by genuine teamwork. This is where technical discussions and exchanges take place. We discuss the requirements with our customers and find the optimal solution together.
Our motivation
