Thanks to the digital data transmission, only the dew oint sensor has to be calibrated. The disply devices remain wired on site.
From - 80 - 20 °Ctd
Control and calibration set guarantee a defined humidity by means of a satured saline solution.
The control and calibration set is screwed onto the dew point sensors and thus enables an easy and low-priced possibility for on-site control and calibration down to - 20 °C dew point.
