The measurement of relative humidity in industrial processes is becoming increasingly critical. Like any measuring device, the question concerning the verification, adjustment or calibration of this type of probe comes up frequently.
Means exist to meet this need, from the simplest to the most complex, depending on the level of uncertainty sought.
After having briefly presented the theory on humidity measurement, we will review the various verification or calibration systems (humidity generator) available on the market today:
- Diluted saline solutions
- Saturated salt solutions
- Dilution system
- Dual temperature generator
- Dual pressure generator
- National reference
