    • Thermometers with Safety Coating

    • Rugged encapsulation protects these instruments from splintered glass or display-fluid leakage (such as exiting mercury or alcohol). An impact-resistant tip allows them to be used under laboratory conditions as precision stir devices, for research and educational purposes or in rugged industrial environments. The protective coating is remarkable for its high transparency allowing easily legibility, for its temperature resistance (up to 250 °C) and hence sterilisable, and for a high degree of acid and alkali resistance (e.g. hydrofluoric acid).

      Benefits of Safety Coating

      • No infiltration through mercury leakage or splintered glass, even with cracked capillary
      • High transparency for easy legibility
      • No contamination of measured media
      • For diameters of up to 9.75 mm
      • For temperatures of up to 250 °C
      • Resistant to most chemicals
      • Available for most types of thermometers, e.g. precision laboratory, general-purpose, or contact

    • 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.
