NCS-CEMS
Description
Featured with stable and reliable performance, high degree of automation and ppb-grade high detection sensitivity, NCS-CEMS volatile organic compounds online monitoring system is produced by conducting in-depth development and integrated design of the advanced technology introduced from abroad. By adopting the measuring principle of gas chromatography photo-ionization Detector (GC-PID), gas chromatography ion mobility spectrometry (GC-IMS) and hydrogen flame ionization detector (FID), this instrument can follow the measurement requirements, and continuously measure the constituent contents of non-methane total hydrocarbon, ammonia and other toxic gases in exhaust gas. This system is suitable for the automatic and continuous on-line monitoring of volatile organic compounds emitted by pollution sources.
The entire system has such characteristics as simple structure, wide dynamic range, strong real-time performance, flexible networking and low running cost. At the same time, due to the adoption of modular structure and convenient combination, this system can communicate with the data system in environmental protection department for networking communication.
Feature
Automatic calibration and automatic zero correction, no need for manual operation, and little maintenance.
Adoption of dual cycle PID system, no need for any carrier gas, and low safety maintenance.
Intrinsic safety type installation and high explosion-proof grade.
In possession of electronic flow control function which can automatically adjust the flow.
Instrument fault self-diagnosis and alarm function. In case of instrument failure, the relay outputs the alarm signal.
Built-in large flow sampling pump, provided with whole range high temperature heat tracing which can minimize the loss of sample adsorption and improve the measuring accuracy.
