KE-2020 VOC Online Monitoring System Introduction: KE-2020 VOC online monitoring system is an analytical instrument for the detection of volatile organic compounds such as non methane total hydrocarbons and benzene series. The online monitoring system is mainly composed of sampling system, analysis system, control system and gas supply system. The system adopts the principle of gas chromatography analysis and is produced in strict accordance with the standard. characteristic: 1. Unique column switching and combination technology; 2. Modular design, highly integrated instrument circuit, and extremely stable operation; 3. The internal analyzer adopts FID dual detector, which has various functions such as power on self-test, power off protection, automatic restart, automatic calibration, etc. The whole instrument has high sensitivity, high stability, and high repeatability; 4. The whole process high temperature is about 140 ℃, the heat tracing sample is transmitted, the sample has no residue, and the analysis range is wide (linearity>107); 5. Built in integrated industrial control high-definition color LCD touch screen display, the software adopts layered modular design, and the operation interface is simple and easy to control; 6. The whole system software has the functions of automatic recording, storing data and atlas, automatic diagnosis and fault alarm, and can set conditions to query and display historical data. The whole system is also equipped with RS232/RS485/4-20MA/Ethernet and other data transmission methods, real-time communication, and access to enterprise monitoring center and environmental protection department monitoring platform; 7. Provide customized solutions: if explosion-proof is required in the installation area, explosion-proof analysis cabin or explosion-proof model can be customized to meet safety and environmental protection requirements. Technical parameters: Detection principle: GC-FID or FID Detection objects: methane, non methane hydrocarbon, benzene, toluene, xylene, etc Range: 0-5000ppm (range can be expanded) Detection limit: ≤ 0.1ppm (methane); ≤ 0.5ppm (non methane hydrocarbon) Analysis time: direct FID ≤ 1s; GC-FID ≤ 1 minute Indication error: ≤± 2% F. S Range drift: ≤± 1% F.S/24h Zero drift: ≤± 2% F.S/24h Response time: ≤ 300 seconds (non methane hydrocarbon) Power supply: 220VAC Signal output: RS232 communication/RS485 communication Gas source: hydrogen, nitrogen or zero grade oxygen Size: 19 inch standard cabinet
