PRODUCT DESCRIPTION

The room CO2 transmitter device uses a highly

accurate and reliable nondispersive infrared (NDIR)

sensor in an attractive, low profile enclosure for

room 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 technology features ensure

optimum measurement stability for both periodic

and constant occupancy applications, so the device

is equally suitable for a classroom or a hospital

room.

Standard features include a field selectable

output signal of either 4-20 mA, 0-5 Vdc or 0-10

Vdc for the highest versatility, programmable CO2

measurement span, a backlit alpha-numeric LCD

and easy menu operation for configuration.

Optional features include a resistive temperature

sensor output (with LCD display of temperature

in either °C or °F), 2 button setpoint adjustment,

a control relay with programmable setpoint,

hysteresis and time delay, and a dry-contact

override switch.
