Humor 20 Humidity Calibration
For manufacturers who need to calibrate their own humidity sensors or probes, the Humor 20 is a portable, highly accurate (±0.3% RH), two pressure calibrator that uses the same primary method used by the National Institute of Standards (NIST) for RH calibration. The calibrator allows for rapid adjustment (< 2 minutes) of humidity from 10% to 100% RH.

The rapid response of the chamber results from the fact that the temperature in the chamber stabilized at a uniform temperature (3-5ºC above ambient). As a result calibration can only be made with this device at one temperature. Many users have successfully certified the Humor 20 as a calibration laboratory.
