VAISALA's 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. Usually two or three different salt solutions, which are chosen according to the application are used.
The structure of the HMK15 is designed to ensure fast and stable temperature equilibration. No external power is required. In addition to laboratory use it is also suitable for on-site checks due to its design that allows transportation.
