Medical Mainstream EtCO2 Sensor Module CM2201CM2201

Metabolic carbon dioxide (CO2) in the blood is carried to the lungs and exhaled, and EtCO2 levels can reflect the somatic status. Cubic medical mainstream EtCO2 sensor module CM2201 is designed with advanced dual beam non-dispersive infrared technology, and widely used in monitoring the respiratory end tidal CO2 concentration and respiration rate. It can be easily integrated to monitors or anesthesia machines with an 8-pin socket and the preparation of the corresponding display/control software.
