Rotronic HF3 HVAC TRANSMITTER

R-Type / S-Type

Measures relative humidity and temperature and calculates the dew/frost point in offices and rooms where good looks play a role.

W-Type / D-Type

Measures relative humidity and temperature and calculates the dew/frost point in HVAC applications focused on relability and repeatability.
