Ambient air non-methane total hydrocarbon online monitoring system

Ambient air non-methane total hydrocarbon online monitoring systemAQMS-900VI/VII

Product Description

AQMS-900VI/VII ambient air/factory boundary NMHC online monitoring system relies on Belgian ORTHODYNE S.A. chromatography technology. Snowdiron independently developed the MODEL 6000 industrial gas chromatograph. It adopts two technical routes: direct method and differential subtraction method to automatically monitor ambient air. The concentration of non-methane total hydrocarbons, benzene, toluene, xylene, halogenated hydrocarbons and other gas components can meet the different application needs of customers.

Features

The direct method/subtraction method is used to monitor non-methane total hydrocarbons, which complies with national standards and policy requirements;

The direct method is designed to measure non-methane total hydrocarbons through enrichment, without interference from other substances (O?, N?, H?O), with low detection limit, and meets the requirements of the "Technical Regulations for Continuous Automatic Monitoring of Non-methane Total Hydrocarbons in Ambient Air (Trial)";

The independent low-temperature enrichment and high-temperature thermal analysis sampling unit significantly reduces the detection limit of characteristic components such as benzene series;

Using a hydrogen flame ion detector, it automatically ignites and resumes operation when power is turned on and after a power outage. The hydrogen electronic valve automatically closes when the flame is extinguished to protect the automatic alarm function;

Equipped with multi-point automatic quality control function, multiple concentration standard gases are regularly introduced to the system for quality control inspection and automatic multi-point calibration;

The measurement range is adjustable and has functions such as concentration over-standard alarm and fault alarm;

It has China Environmental Protection Product Certification (CCEP), Measuring Instrument Type Approval Certificate (CPA), CMA mark test report, explosion-proof certificate, etc.
