No measuring instrument stays accurate by itself. It is essential that the functioning of an instrument is periodically checked against a reference.

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
  • Calibrated precision mercury thermometer
  • 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
  • Easy and reliable calibration of humidity probes and transmitters
  • Based on saturated salt solutions
  • Suitable for laboratory use and on-site checks
