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.
