Insert Type CO

2

 Concentration Transmitter

CY8000C

General

The CY8000C insert type CO

2

 concentration transmitter

detects the concentration of carbon dioxide (CO

2

) in ducts

and other test sites.    The CY8000C can be used in a
wide range of applications such as monitoring of CO

2

concentration in retain ducts and the control of outdoor air
intake.

Features

1) Non-dispersive infrared absorption method (NDIR)
2) Linear output signal in 1 to 5 VDC range
3) Stability over prolonged use

Model

Model No.
