The HT-670x Series wall mount and duct probe humidity transmitters use a patented All-Polymer sensor capable of sensing the entire range of 0 to 100% RH. Both transmitters feature a quick-mount, two-screw design, saving time and simplifying installation. A combination wallbox and surface mounting base connects to the unit for easy mounting directly to either drywall (spring clips provided) or a standard U.S. wallbox. All wiring connections for the humidity transmitters terminate on terminal blocks. The Johnson Controls TRUERH duct package offers an all plastic enclosure, which reduces thermal for improved accuracy.
