The Si-PRO-U-I-100-H is an interchangeable, heated hygrometry probe for Si-C320 transmitters and it has been designed for being used in environments where there is constant high humidity or rapid oscillanting humidity where the probe’s performance and its tolerance to pollutants are key. Stainless steel body and sintered filter. Length 100 mm (3.94’’), Ø 13 mm (0.51’’).  
It delivers dewpoint and frost point as a measurement. The relative humidity value, as well as the rest of psychrometric values can be calculated when the Si-PRO-T-150 temperature probe or an additional external temperature probe is connected to the Si-C320 transmitter using the Si-ACC-ETP adapter.

Main applications: industrial processes, air handling units, drying processes, pharma production machines.

*[Si-ACC-R2](https://sauermanngroup.com/en-INT/node/34904) probe cable for connection to class 320 transmitters is needed.*
