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.
