Overview
The CMS-6000 Environmental Air Non Methane Total Hydrocarbon Monitoring VOCs Online Monitoring System analyzes the content of non methane total hydrocarbons and benzene derivatives in the factory boundary/plant area, and combines meteorological parameters to form a report on the upper computer of the monitoring system. The report is uploaded to the environmental protection platform through a data acquisition instrument using the standard HJ 212 protocol to meet the monitoring requirements of the environmental supervision department. At the same time, the data can be transmitted to the DCS system of the park or factory area, making it convenient for the central control room to monitor the real-time concentration of each monitoring point in the factory area; Integrating security design, automated monitoring, intelligent supervision, and fast and timely alarm.

Product Overview
Used for monitoring non methane total hydrocarbons in ambient air（NMHC concentration. Adopting a dual valve, dual column, and FID configuration, with high-temperature tracing throughout the process, the sample is quantified by a quantitative loop, injected with dual valves, and separated by dual chromatographic columns before entering a hydrogen flame ionization detector (FID) for detection. The total hydrocarbon (THC) and methane (CH4) concentrations in the sample are measured separately.

Gas dynamic calibrator
Gas dynamic calibrator（PR-6100 is an intelligent online gas calibration instrument. The traditional calibration method uses multiple steel cylinder gases of different concentrations to be injected and analyzed separately, and instrument calibration is performed through calibration curves. It consists of a flow control system, a gas path control system, and a computer control system. A known concentration standard gas is used to adjust different dilution ratios to obtain concentration gradients of standard gases with different contents. Fully automated operation, significantly reducing workload and saving gas distribution time.

samplingsystem
The integrated sampling probe mainly consists of an air filter, a sampling rod, and a rain cover.
（1) Sampling device: Vertical laminar flow sampling manifold.
（2) Sampling head: prevents rainwater and coarse particles from falling into the main pipe, while also preventing birds, small animals, and large insects from entering the main pipe. The design of the sampling head should ensure that the sampling airflow is not affected by wind direction and enters the main pipe stably.
（3) Sampling manifold: The inner diameter of the manifold is selected to be 4cm, and the airflow inside the sampling manifold should maintain laminar flow, with low power consumption and safe voltage; Stable laminar airflow, good system airtightness, split structure, easy installation; Heating to keep dry during maintenance without cleaning, and sealing during non working conditions; The material of the sampling manifold should be stainless steel or polytetrafluoroethylene;
Airflow state parameters:
（4) Preprocessing: The preprocessing unit collects, filters, stabilizes, calibrates, and automates the sample gas, ensuring that the sample meets the operating requirements of the online analytical instrument without distortion, and guaranteeing the long-term, reliable, and accurate operation of the online analytical instrument.
The entire preprocessing unit is integrated into the cabinet, with a disk mounted structure that is aesthetically pleasing and stable;
