Jintan Taina Design Portable Infrared CO/CO2 Analyzer Concept

1. Design and use industry

A high-precision instrument for detecting toxic and harmful substances in the air of public places and workplaces. The instrument uses non dispersive infrared principle (i.e. selective absorption of CO/CO2 gas by infrared spectrum) to measure the concentration of CO/CO2 in the air. It has the advantages of high measurement accuracy, long service life, and low cross interference. It is an instrument in the fields of environmental monitoring and occupational health monitoring. This instrument is widely used in environmental protection, environmental monitoring, health supervision, occupational health, disease control, and research institutes.

2. Design adopts standards
