CEMS-V100 on-line monitoring system for volatile organic compounds (VOCs) is an on-line monitoring device for VOCs in flue gas developed by Tian Rui instrument. It can measure a variety of organic compounds such as total hydrocarbon (THC), methane (CH4), non methane total hydrocarbon (NMHC), benzene series (BETX) and so on. The system can be widely used in the VOCs emission monitoring of various industrial pollution sources, such as semiconductor, electronic, pharmaceutical, petrochemical, chemical, printing, automobile, coating, rubber and other industries. The performance is stable and reliable, and the degree of integration is high. At the same time, according to various operating conditions and customer needs, Tian Rui can provide customized solutions, including: explosion-proof cabinet type, the whole process of high temperature hot, mobile monitoring car, etc.

Performance advantage:

The GC-FID method is adopted in the analysis, which is in line with the national standard method HJ/T 38-1999 and the US EPA standard.

Various detectors such as ECD, FPD and TCD can be selected to meet the needs of different sensitivities and detectable substances.

The system has high detection sensitivity and can automatically switch at high and low ranges. The target analytes have independent detection limits.

The standard analysis time is 1 minutes, which can provide real-time and continuous monitoring data.

High degree of automation, automatic pipeline cleaning, instrument maintenance workload is small.

It has the function of real-time / timed system diagnosis and fault alarm.

Built in calibration module, calibration cycle can be set up, automatic instrument quality control can be realized.

The FID detector has the function of automatic ignition. After the flame is extinguished, the gas system is automatically turned off to ensure the safety of the system.

Built in integrated industrial control machine, high-definition color LCD touch screen display, the system software is hierarchical modular design, operation interface is simple and easy to control;

It can display the running status of each part of the system in real time, and set up the parameters of the instrument and maintain it conveniently.

It can view real-time / historical monitoring data, automatically store data and maps, and provide various forms of reports to choose from.

With RS232/485, RJ45, USB and other data transmission modes, real-time data communication can be realized and access to environmental protection department monitoring platform.

It has the functions of operation restriction and password control to prevent operation errors or ultra vires operation.

Customized solutions can be provided according to customer needs, including explosion-proof cabinet type, whole temperature high temperature tracing mode and mobile monitoring vehicle type.
