    Dusty desiccants should be avoided as the dust may be passed in to the HygroGen chamber. Material Safety sheets for the desiccants supplied by ROTRONIC are available on request. 2.6 Molecular Sieve Desiccant (Factory Standard) Molecular sieves have the appearance of small opaque tan beads.

    For most situations it recommended that new silica gel is used unless a proven process for regeneration can be implemented. Regeneration can be carried out repeatedly, although eventually the beads will lose their colour. Replacement Orange to Green self-indicating silica gel can be ordered from ROTRONIC. 2.10 Drierite Desiccant Drierite is anhydrous calcium sulphate.

  • Page 32: Practical Guidance - Chilled Mirror Reference

    Document title 6.4 Chilled Mirror Humidity Reference For the lowest possible calibration uncertainty, the ROTRONIC recommendation is to use a chilled mirror instrument to provide the best possible reference humidity (contact ROTRONIC for details of tested chilled mirror systems). This type of instrument is generally accepted as a secondary humidity standard.
