PRODUCT DESCRIPTION
The duct CO2 transmitter uses a highly accurate and
reliable non-dispersive infrared (NDIR) sensor in an
attractive enclosure with a gasketed, hinged cover
for duct applications to monitor CO2 levels. The
sensor uses dual wavelength optics and LTA (long
term adjustment) signal processing technology
to deliver industry leading long term accuracy
and reliability. These features ensure optimum
measurement stability for continual monitoring of
either supply or return air measuring.
Optional features include a resistive temperature
sensor output (with LCD display of temperature in
either °C or °F), a control relay with programmable
setpoint, hysteresis and time delay, and either a
conduit or cable gland connection point.
