DigiTH is an air humidity, temperature and dew point sensor with RS485 modbus interface. The sensing elements are located on a PCB in the tip of the sensor. The acquisition circuit is completely over-moulded. Temperature and humidity sesor is based on a precision SENSIRION? sensor. Each sensor is individually factory-calibrated.With dimensions of only 108mm x 16mm, the sensor can easily be fitted into many standard radiation shields and field application.

■ Air humidity and temperature sensor with dew point
