Gas AnalysisNon Dispersive Infrared Gas Analyzer (NDIR) SR-2000Ex (Flameproof Type)
Introduction
The SR-2000Ex explosion proof infrared gas analyzer can be used to detect the designated gas content in mixed gas backgrounds such as CO, CO2, CH4, SO2, NH3, H2O, NOx and other hydrocarbons. The explosion resistant gas analyzer will avoid explosions, even if the machine breaks down or sparks at high temperatures.
Features
- Non-dispersive infrared rapid gas analysis technology
- High accuracy infrared detector with integrated interference filters
- New electrical modulated infrared light source, filming gas chamber which is easy to disassemble, embedded data acquisition system.
Gases to be detected
Diatomic molecular gas: CO, CO2, CH4, NH3, SO2, NOx and hydrocarbons, etc.
