TH-2001 chemiluminescence method NOx Analyzer
Applications
Based on the gas phase chemiluminescence principle, the TH-2001 chemiluminescence method
NOx Analyzer uses modern micro single chip techniqueto detect, control and process signals. It is one of the hightech serial automatic ambient air monitoring products combined the photology,
machinery,electronics, photochemistry and modern sensor techniques and can continuously monitor
trace NO,NO2 and NOx concentrations in ambient air.
Features
Full Chinese menu-drive screen and five-key with function instructions operation simplify operationprocedures.Auto alarm indicator facilitates fault determination and decreases failure rate.Modular design is easy for daily maintenance and repair.Double-line and single passage time-sharing sampling for gas path system.Specifications
