Accessory is designed to verify the measuring accuracy (calibration) and new adjustment of instruments sensing the air relative humidity. Relative humidity is generated in air-tight vessel fixed to relative humidity probe. The value of relative humidity is depends on chemical solution applied inside of the vessel.
