3.1 GENERAL DESCRIPTION
The AMC-310 AirSense is a non-dispersive infrared analyzer for measuring environmental CO
concentration in ventilation systems and indoor living spaces. Its measurement range of
0 – 5000 ppm (parts per million; 1000 ppm = 0.1%) covers the range required to monitor
compliance with ASHRAE or other ventilation efficiency standards.
Packaged in a compact enclosure, the Model 310 can be discreetly installed anywhere from the
boardroom to the boiler room. Standard center wiring access and fully floating outputs make
installation a snap. The Model 310 provides several output alternatives. A voltage or 4 – 20 mA
current output is standard. An optional LCD readout is available. An optional relay contact can
be configured to open or close above a user-adjustable set point. A simple one-point calibration
procedure and a built-in calibration port that requires no special fittings or adapters make the
Model 310 simple to maintain.
