Humidity transmitters with temperature output for duct
RHT Duct is a relative humidity transmitter with temperature output installed in air ventilation duct. Illuminated display ensures easy readability also from a distance. The RHT has a screwless lid and an easily adjustable mounting flange that make the installation of the device easy.
RHT Duct series devices include:
• Separate output for each measurement parameter (rH and T)
• Offset feature enabling field calibration for each measurement parameter (rH, T)
• Mounting flange
RHT Duct series device options offer:
• Clear backlit display
• Modbus RTU interface
• 4-20 mA proportional output
