Calibration Furnaces for Realizing ITS-90 Fixed Points or Comparison Calibrations
Precise Temperature Measurements for the Highest Demands: Discover our Calibration Furnaces for Primary Laboratories, Science, and Research
In precise temperature measurements, calibration furnaces play a crucial role, especially in primary laboratories, scientific institutions, and research environments. These devices are used primarily for the fixed-point calibration of resistance thermometers and thermocouples to ensure exact and reliable temperature measurements.
ISOTECH calibration furnaces enable an extremely long plateau phase – both during melting and solidification of fixed-point cells – thus meeting the recommendations of CCT/2000-13 “Optimal realization of the definition of the fixed points of the ITS-90.”
Furthermore, our calibration furnaces are also optimally suited for comparison calibrations, as they offer extremely good stability and excellent homogeneity. The advantage of comparison calibration is the freely selectable calibration points.
With ISOTECH calibration furnaces, you achieve the smallest measurement uncertainties even at extremely high temperatures.

Precision in a Slim Format: Discover our Calibration Furnaces
for Slim Temperature Fixed Points
ISOTECH calibration furnaces for slim temperature fixed points are faster and more compact compared to large precision calibration furnaces. Due to their smaller volume, they are particularly suitable for comparison calibrations or the use of slim temperature fixed points. With these products, we offer you a more cost-effective solution that saves space and operates efficiently.
