DESCRIPTION:
The CO2 monitor uses a highly accurate and reliable Non-dispersive Infrared (NDIR) sensor with state-of-the-art
digital linearization and temperature compensated circuitry in an attractive, low profile enclosure for room
applications to detect CO2 levels and provides a linear analog signal output of 4-20 mA, 0-5 or 0-10 Vdc signals. An
onboard relay can provide a control signal based on a high limit setting. Parameters are set up via momentary
pushbutton (keypad) and the LCD display which is also used to display current reading.
