Infrared CO/CO2 Analyzer

Product Overview

The HD-HW300A Infrared CO/CO2 Analyzer is a high-precision instrument developed for inspecting toxic and harmful substances in the air of public places. The instrument uses the non-dispersive infrared (NDIR) principle to measure the concentrations of carbon monoxide and carbon dioxide in air, with the advantages of high measurement accuracy, long service life and small cross-interference, and is an indispensable instrument in the fields of environmental monitoring and occupational health monitoring.

Application Range

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