The Rotronic calibration devices are small, airtight chambers that precisely fit Rotronic probes. The lower part of the device consists of a screw-on lid into which the humidity standard is poured onto an absorbent textile pad. The specified humidity is generated in the calibration device after a stabilization period of 30 to 180 minutes. The probe can then be calibrated or adjusted in comparison with the reference value of the humidity standard.
