SCS* Humidity Standards
These humidity standards from ROTRONIC are supplied in packs of 5 hermetically sealed ampoules of the same humidity level. Each ampoule is labelled with the humidity value and a serial number. The values most commonly used are 35 %rH and 80 %rH. These are used for 2-point calibrations. With the exception of the 0 %rH standard the ampoules contain an unsaturated saline solution. For the 0 % standard we use highly porous ceramic material (a molecular sieve). Each set is supplied with an SCS certificate which guarantees the traceability and accuracy of the humidity standards used for calibration purposes.

Calibration Devices
These are small, airtight containers which fit exactly onto the respective sensor and form an airtight enclosure around the sensor. The lower screw-on part is then filled with the humidity standard material. The desired humidity level is reached following a settling period of typically 60 minutes at a constant temperature. The equipment can now be adjusted to match the reference humidity value. We offer suitable devices for every ROTRONIC sensor and can also construct an appropriate calibration device for your humidity measurement equipment.
