Infrared CO/CO2 analyzer

I. Product Overview

The infrared CO/CO2 analyzer is a high-precision instrument for detecting toxic and hazardous substances in the air of public places. It utilizes the non-dispersive infrared (NDIR) principle to measure the concentrations of carbon monoxide and carbon dioxide in the air. It offers high accuracy, long service life, and minimal crosstalk, making it an essential instrument for environmental and occupational health monitoring.

II. Scope of Application

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