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
