HMK15 Humidity Calibrator Set

The Vaisala Humidity Calibrator HMK15 makes calibration and spot checking of humidity probes and transmitters easy and reliable. The operating principle of the HMK15 is based on the fact that a saturated salt solution generates a certain relative humidity in the air above it. The reading of the humidity probe or transmitter can then be adjusted accordingly.

The package includes:

  • Two salt chambers, chamber covers and transportation covers
  • Base plate
  • Measurement cup and mixing spoon
  • Certified and pre-measured packed salts: LiCl (11%RH) and NaCl (75%RH)
  • Ion-exchanged water
  • Soft insulated carrying bag
  • User's Guide in English
