  (-196 °C to + 1200 °C)

ludwig schneider Water triple point cells

Water triple point cells from Ludwig Schneider are filled with high-purity water. This water is gas-free and has the same isotope composition as ocean water.

Before filling, the cells are chemically cleaned with a special cleaning procedure. This is the reason for the low drift of this type of cell, which is less than 0.01 mK/a.

Water triple point cells are maintenance-free and are mainly used for the calibration of platinum resistance thermometers.

• Measurement tolerances of just a few mill kelvins.


• On request, also available with internationally recognised DAkkS certificate (ILAC).
