cGas Detector Analog Transmitter - Operation Manual
2 INTRODUCTION
2.1 General Description
Thank you for purchasing our cGas Detector Analog Transmitter, a single
channel CO
2
gas detection designed for use in non-explosion rated, commercial
applications that require continuous monitoring of Carbon dioxide. It offers one
4-20 mA analog output and is ideal for applications where compressed CO
2
is
used and stored, climate control in commercial buildings and other processes
requiring the continuous monitoring of CO
2
.
The sensors utilized in this device are accurate enough to measure to
Occupational Health & Safety (OHS) hazardous levels for toxic gases. The
transmitter operates by diffusion.
