The Vaisala HMK15 humidity calibrator makes the calibration and spot checking of humidity probes and transmitters easy and reliable. The HMK15 operates on the principle 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.

To calibrate, a sensor head is inserted into a salt chamber containing a saturated salt solution. The probe/transmitter reading is then adjusted to the humidity that the specific salt solution generates at that particular temperature. Calibrations are usually performed at least at two different humiditys to ensure accuracy over the entire humidity range. There are four holes in the chamber cover designed for probes and transmitters with 12 mm, 13.5 mm (2 each) and 18.5 mm diameters.

The Vaisala HMK15 humidity calibrator is suitable for both laboratory and filed usage. During transportation, the chambers can be tightly closed with specially designed transit covers.
