Relative Humidity and Relative
Humidity/Temperature sensors
monitor and transmit changes
to building control systems for
precise control. Several models
are available for humidity only
(in 5%, 2% and 2% certified) or
for humidity and temperature
sensing (also in 5%, 2% and 2%
certified versions). All 2% and
2% certified versions feature a
removable, replaceable sensing
tip. The humidity only units are
available in either 0 to 10 Vdc
or 4 to 20 mA outputs.
Combination humidity and
temperature units are also
available in either dual current
or voltage versions,
transmitting proportional
signals back to the controller
Liquid Crystal Display versions
show Fahrenheit or Celsius
readings.

Outdoor Air Humidity Sensors
QFA3xx with
AQF3100
Standard models available are
2% and 2% certified, for both
humidity only and combination
humidity with temperature
sensing. A removable,
replaceable sensing tip enables
these sensors to be recalibrated
within seconds. Sensors are
offered with either 0 to 10 Vdc
or 4 to 20 mA outputs.
