High Concentration CO

General

The CH-CO2 (sensor for wall mounting) and

designed to measure carbon dioxide (CO

) concentration up to 30 vol.%.

The unit is designed for connecting to controllers, Direct Digital Control (DDC) or other system

with 0-10V or 4-20mA signal inputs. The two parallel signal outputs Vo (0-10V) and Io (4-20mA)

give linear signals corresponding to the measuring range of 0 – 20 vol.% carbon dioxide (0-30%

option on request). An additional fresh-air calibration (Cal) command input is added to facilitate the

calibration in the field.
