Humidity transmitters with temperature output for duct that use Modbus serial communication protocol

RHT-MOD Duct is a relative humidity transmitter with temperature output installed in air ventilation duct. In addition to these measured values, RHT-MOD Duct calculates various parameters such as dew point, mixing ratio, enthalpy and absolute humidity. Illuminated display ensures easy readability also from a distance. The RHT-MOD has a screwless lid and an easily adjustable mounting flange that make the installation of the device easy.

RHT-MOD Duct series devices include:

• Separate Modbus output for all measured and calculated parameters (relative humidity, temperature, dew point, mixing ratio, enthalpy and absolute humidity).

• Offset feature enabling field calibration for measurement parameters rH and T.

• Mounting flange

• Clear backlit display
