HUMIDIT Y

HUMIDITY TRANSMITTERS
RHT Series
Wall mount relative humidity transmitters for building automation systems

RHT relative humidity transmitters are engineered for building automation systems in the HVAC/R industry. The RHT measures relative
humidity (rH), and temperature (T). RHT devices are available with
large touchscreen display making conguration of the device quick
and easy.
RHT series devices include:
• tSeparate field configurable output for each measurement
parameter (rH, T).
• tProportional output options including: voltage (0–10 V, 2–10 V)
and current (4–20 mA).
RHT series device options offer:
• t2” x 3” touchscreen display
• tField configurable relay for any of the two parameters
• tModbus configuration
The versatility of the RHT series air quality transmitters ensures that
the right product for your application is available.

APPLICATIONS
RHT series devices are commonly used to monitor:
• thumidity and temperature levels in offices, public spaces,
hospitals, meeting rooms and classrooms
• thumidity and temperature in various commercial applications
• thumidity and temperature in HVAC/R environment
