Temperature and Humidity Sensor Comet P8641 four-channel p-line Web sensor. Connection via Ethernet with PoE power supply. Temperature measurement range from -55 to +105 °C. PoE (Power over Ethernet) power supply is supported.

Sensor for digital probes of temperature and relative humidity (up to 4 measured variables). The measured temperature and relative humidity are further recalculated into other humidity expressions - dew point temperature, absolute humidity, specific humidity, mixing ratio, or specific enthalpy. The price of the device automatically includes a COMET calibration certificate.
