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.
