Portable Carbon Monoxide Gas Analyzer

1. Product Overview:

The portable carbon monoxide gas analyzer is a high-precision instrument developed by Shandong Holder Electronic Technology Co., Ltd. for checking toxic and harmful substances in the air of public places. The instrument uses the non-diffusion infrared principle to measure the concentration of carbon monoxide in the air. It has the advantages of high measurement accuracy, long service life, and low cross-interference. It is an instrument equipped in the field of environmental monitoring and occupational health monitoring.

2. Scope of application:

The portable carbon monoxide gas analyzer is widely used in environmental protection, environmental monitoring, health supervision, occupational health, disease control and scientific research institutes.
