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.
