Description
The measuring of CO is based on an optical principle
2
(NDIR) using advanced optical chamber. Built-in auto-
calibration function ensures excellent long term
stability and accuracy.
CO concentration value is available on the receiver
2
side on analog output or through serial interface
RS485 with Modbus communication protocol.
The sensor efficiently controls ventilation systems,
based on actual room air quality.
Low battery power is indicated by a built in LED
indicator.
