The Novus RHT-WM (Wall-Mount) and RHT-DM (Duct-Mount) transmitters are high-performance industrial sensors designed for precise and stable humidity and temperature monitoring in HVAC, environmental, and process-control applications. Using advanced capacitive sensing technology, the RHT series provides fast response, excellent repeatability, and long-term stability—even in demanding industrial environments.

Both models offer reliable analogue or digital output signals (depending on version), allowing seamless integration with BMS systems, PLCs, industrial controllers, and data-logging equipment.
