Description

The HX71 Series relative humidity sensor/transmitter provides a reliable and economical method for most relative humidity monitoring applications. The compact design is ideal for wall or duct mounting. Each unit is factory calibrated to provide excellent sensitivity, fast response, and stability. The unit features a simple installation and hookup. The linearized current or voltage output permits interfacing with most display and control devices like meters, controllers, recorders, and data loggers. The design features a 316 SS NEMA 4 (IP66) housing and includes a shielded output cable with stripped wire leads. A mounting kit is available that allows for wall or duct mounting.
