Portable Carbon Dioxide Gas Analyzer

1. Product Overview

The infrared CO2 analyzer is a high-precision instrument used by our factory to inspect toxic and harmful substances in the air of public places. The instrument uses the non-diffusion infrared principle to measure the concentration of 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.

2. Scope of application

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

3. Standards adopted

JJG635-2011 "Carbon Monoxide and Carbon Dioxide Infrared Gas Analyzer"

GB/T18204.2-2014 "Public Place Hygiene Inspection Method Part 2: Chemical Pollutants"

GBZ/T 300.37-2017 "Determination of Toxic Substances in Public Places Part 37: Carbon Monoxide and Carbon Dioxide"
