Description

Description

The HX71 Series relative humiditysensor/transmitter provides areliable and economical method formost relative humidity monitoringapplications. The compact design isideal for wall or duct mounting. Eachunit is factory calibrated to provideexcellent sensitivity, fast response,and stability. The unit features asimple installation and hookup. Thelinearized current or voltage outputpermits interfacing with most displayand control devices like meters,controllers, recorders, and dataloggers. The design features a316 SS NEMA 4 (IP66) housing andincludes a shielded output cablewith stripped wire leads. A mountingkit is available that allows for wall orduct mounting.
