The calibration device is a small airtight container that fits on the probe and seals around the humidity sensor. During calibration, a known reference humidity is produced inside the calibration device by means of a humidity standard (usually an aqueous salt solution).

 

For HCD probes, Rotronic offer the ER-15: for 15mm diameter probes.
