Industrial Gas Analyzer for Explosion-Proof NDIR Gas Analyzer
Industrial Gas Analyzer for Reliable Multi-Gas Monitoring
The industrial gas analyzer from Instrava is designed for accurate and continuous monitoring of industrial process gases using advanced NDIR (Non-Dispersive Infrared) technology. This technology provides reliable gas concentration measurement with high sensitivity, strong anti-interference capability, and long-term stability.
The analyzer supports measurement of multiple gases including CO, CO₂, CH₄, NH₃, hydrocarbons (CnHm), sulfur hexafluoride (SF₆), and sulfur dioxide (SO₂). With high accuracy (≤±2% F.S.) and resolution up to 0.01%, the system is suitable for industrial applications that require precise gas composition monitoring and emission control.
Equipped with an explosion-proof housing (ExdIICT6 / ExtDA21 IP65), the analyzer can operate safely in hazardous industrial environments, providing stable performance even in demanding process conditions.
