CO2 sensor ACD10
ACD10 is a sensor detecting the concentration of CO2 in the air based on the non-dispersed infrared (NDIR) principle. ACD10 consists of a precision optical path, a high-precision detection circuit, and a component to detect infrared absorption for gas sensing. ACD10 has good selectivity, no obvious oxygen dependence, and long life. It has a digital output, which makes it easy to use.
Compatible with LK4 and LK3.5.
