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 adopts the non diffusive infrared principle to measure the concentration of carbon monoxide and carbon dioxide in the air. It has the advantages of high measurement accuracy, long service life, and low cross interference. It is an essential instrument in the field of environmental monitoring and occupational health monitoring.

Applicable scope

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