SN274 | CO2 External Probe

CO2 concentration sensor for Datalogger U2422

CO2G-xx probe with the I2C output is designed to measure carbon dioxide concentration in the air in chemically non-aggressive environments. The CO2 measurement is based on the dual wavelength NDIR principle, which automatically compensates for ageing effects. The probe is IP65 rated and the replaceable filter offer protection in harsh environment. It is designed for connection to COMET devices equipped with input for external CO2 probes. The probe is interchangeable, the calibration constants are saved in the internal memory of the probe.

A multiple point CO2 and temperature adjustment procedure leads to excellent CO2 measurement accuracy over the entire temperature working range; this is a must for process control and outdoor applications.

PROBE IS COMPATIBLE ONLY WITH DEVICES MANUFACTURED FROM 04/2023.
