  • Lithium chloride generates a reference humidity of approximately 11 %RH. It is normally used as the dry end (offset) reference.

    CAUTION Never add water to dry LiCl salt; the salt may heat up so rapidly that it splashes out of the chamber.
    CAUTION LiCl is harmful when swallowed; the solution is also corrosive.
    If the LiCl solution is used or stored in temperatures below +18 °C (+64 °F), its equilibrium humidity changes permanently.
  • Magnesium chloride generates a reference humidity of approximately 33 %RH. It is often used as a checkpoint if calibration is performed at more than two points.
  • Sodium chloride generates a reference humidity of approximately 75 %RH. It is used as the wet end reference (gain) for probes measuring in applications with normal humidities.
  • Potassium chloride generates a reference humidity of approximately 85 %RH.
  • Potassium sulphate generates a reference humidity of approximately 97 %RH. Potassium sulphate is used as the wet end reference (gain) for probes measuring in applications with very high humidities, 90 … 100 %RH (for example, outdoor and concrete measurements).
