Introduction

The AirSense Model I-310e is a non-dispersive infrared
analyzer for measuring environmental CO 2 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, distinctively styled enclosure, the
Model I-310e can be discreetly installed anywhere from the
board room to the boiler room. Standard center wiring
access and fully floating outputs make installation a snap.
The Model I-310e 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 setpoint.
Terminals for connection to an optional thermistor are
available. With the correct thermistor installed A direct
temperature input can be provided to the controller.
A simple one-point calibration procedure and a built-in
calibration port that requires no special fittings or adapters
make the Model I-310e simple to maintain.

Displays and Indicators

The basic Model I-310e has a single green LED on the front
panel which illuminates whenever the unit is operating. This
LED is on steadily when the measured concentration is
below the high CO limit, and blinks whenever the
2
concentration is above the limit.
The standard factory high limit is 1000 ppm, but can be
easily adjusted in the field. The procedure for adjusting the
high CO limit is described on page 11.

The display option adds a 4 digit liquid crystal display
(LCD) to the front panel. The display shows the measured
CO2 concentration in parts per million (ppm). 1000 parts
per million equals 0.1%.
