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 millikelvins
  
• Available on request with a DKD/DAkkS or PTB calibration certificate
