Infrared CO/CO2 Analyzer

Product Overview:

The infrared CO/CO2 analyzer is a high-precision instrument used by our factory to detect toxic and harmful substances in the air of public places. The instrument uses the non dispersive infrared NDIR principle to measure the concentration of carbon monoxide and carbon dioxide in the air, and has the advantages of high measurement accuracy, long service life, and low cross interference. It is an essential instrument in the fields of environmental monitoring and occupational health monitoring.

Scope of Application:

This instrument is widely used in environmental protection, environmental monitoring, health supervision, occupational health, disease control, and research institutes.
