NOx analyzer adopts chemiluminescence method and combines with advanced microprocessor technology. It provides accurate and reliable detection of NOx at ppb ppm level which meets the requirements of ambient gas monitoring and online monitoring of pollution source with dilution method. The operation principle is based on chemiluminescence method. After absorbing the chemical energy and the reacting with 03, NO is inspired to excited state and once it returns to ground state, it will release energy in form of light quantum. The intensity of light emission is directly proportional to gas concentration, which could realize quantitative measurement. This analyzer can completely control all functions and also provides online instruction for important work parameters. Real time auto compensation for temperature and pressure will be made during measurement 0Measurement range: O-SOOppb (other rangers are customazible) 0NO, N02, NOX is measured separately 0Multiple functional operations by microprocessor 0Task software is allowed to monitor test data during operation 0Continuous self-checking with alarm function 0Permeation drying tube equipped with ozone generator 0 Bidrection RS-232 port for remote control 0Digital output working parameter 0Response time optimized by signal filter technology of self-adaptior 0Compensation function for temperature and pressure 0USB and Ethernet interface 0Colorful display and screen touch operation 0Large memory and history data saved automatically TIANJIN ZWINSOFT TECHNOLOGY CO..LTD Manufacturerand Exporter ofEnvironmental Monitoring Instruments Email: [email protected] Address: No. 8, Haitai Development 5th Road, Huayuan Industrial Park, Binhai High-Tech Zone, Tianjin
