    is an integral part of long term measurement reliability.

The ROTRONIC calibration accessories permit calibration of our instruments without return to the factory.


 Certified Humidity Standards: the standards are presented in boxes of
5 sealed glass ampoules of the same value. Values range from 0 to 95%RH. With the exception of the 0%RH standard (a desiccant), the ampoules hold a non saturated salt solution.
The standards are manufactured in Switzerland under strict supervision of SCS (Swiss Calibration Service).
Each box of standards comes with an individual certificate that gives all the information required to provide traceability.		 Calibration Device: a small chamber which fits and seals tightly around the end of the probe. The standard is deposited in a small receptacle which screws on to the calibration device.

After 45 to 60 minutes, the standard has conditioned the air inside the calibration device to the proper humidity and the instrument can be adjusted.
