HIGHLY ACCURATE FIXED POINT CELLS
FOR PRECISE CALIBRATION
The water triple point is the most accurately representable fixed point of the 1990 International Temperature Scale (ITS 90). It is 0.01 °C or 273.16 Kelvin. The accuracy is 0.0001 °C. Due to the high thermal equilibrium of this fixed point, the water triple point cell is optimal for high-precision calibration (e.g. e. g. of platinum resistance thermometers).
Quality made in Germany
directly from the manufacturer
Our water triple point cells are made of chemical and temperature resistant borosilicate glass and filled with high purity water after a special chemical treatment. We are the only German manufacturer to produce our water triple point cells ourselves. This allows us to guarantee the highest quality and precision – triple point cells for water “Made by Schneider”.
Unique all-round service by our Ludwig Schneider Messtechnik GmbH
Our DAkkS calibration laboratory is accredited according to DIN EN ISO/IEC 17025:2018 for the measurands temperature and density. We measure temperatures from -196 °C to 1,850 °C and guarantee the highest precision according to all international standards. Together with our extensive product range and our modern calibration laboratory, we offer you a comprehensive all-round service.
