HMK15
No measuring instrument stays accurate by itself. It is essential that the functioning of an instrument is periodically checked against a reference. Vaisala has developed the Vaisala Humidity Calibrator HMK15 to make calibration and spot checking of humidity probes and transmitters easy and reliable.
Features
- Easy and reliable calibration of humidity probes and transmitters
- Based on saturated salt solutions
- Suitable for laboratory use and on-site checks
