Preface

This manual describes the Model 310en of the AirSense 310

Carbon Dioxide sensor family. The 310en, while similar in

external appearance and operation to previous 310e models,

has a slightly modified feature set and differences in the

location and operation of the user interface.

Model Identification

Because of its similarity to previous models, the Model

310en is most easily identified by the prefix "M310en" on

the unit's serial number tag visible on the sensor circuit

board when the cover is removed.

All other AirSense 310e series sensors are covered in the

AirSense Model 310e Operator's Manual.

Introduction

The AirSense Model 310en is a non-dispersive infrared

analyzer for measuring environmental CO 2 concentration in

ventilation systems and indoor living spaces. Its default

measurement range of 0 - 2000 ppm (parts per million; 1000

ppm = 0.1%) covers the range required to monitor

compliance with ASHRAE or other ventilation efficiency

standards. For specialty applications the measurement range

can be easily increased up to 5000 ppm.

Packaged in a compact, distinctively styled enclosure, the

Model 310en can be discreetly installed anywhere from the

board room to the boiler room. Standard center wiring

access, fully floating outputs and power/signal mis-wiring

protection make installation a snap.

The Model 310en provides several output alternatives. A

voltage or 4 - 20 mA current output is standard. An optional

LCD readout is

configured to open or close above a user-adjustable setpoint.
