GA-C131 Carbon Monoxide/Carbon Dioxide Analyzer

Description

GA-C131 Carbon Monoxide/Carbon Dioxide Analyzer

I.Product Overview

Our infrared CO/CO2 analyzer is a high-precision instrument for detecting 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. It features high measurement accuracy, long service life, and low cross-interference, making it an essential instrument in environmental monitoring and occupational health monitoring.
