Digital temperature/humidity probe I2C DIGIS/M-x

The DigiS/M-x digital temperature/humidity probe is designed to measure air temperature and relative humidity in chemically non-aggressive environments. It is equipped with an I2C output and designed mainly to be used in combination with the COMET Multilogger device. The probe is interchangeable (calibration constants are saved in the probe itself).
The temperature/humidity probe is available in different variants depending on the cable length (the last two digits of the probe name indicate the cable length), and is suitable for fixed or portable applications where fast response times are required.
