USER-FRIENDLY MEASURING DEVICES humidity transmitters rht-mod duct series 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. Illuminated display ensures easy readability also from a distance. The RHT-MOD Duct 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 each measurement parameter (rH, T) • Mounting flange • Clear backlit display RHT Duct series devices are commonly used to monitor and control: • Relative humidity and temperature levels of incoming and return air in ventilation system Copyright HK Instruments 2017 www.hkinstruments.fi Datasheet Version 7.0 2017
