Infrared Gas Analyzer for Optic Analysis
Infrared Gas Analyzer for Accurate Industrial Gas Measurement
The infrared gas analyzer from Instrava is designed for high-precision industrial gas analysis using advanced NDIR (Non-Dispersive Infrared) technology. This measurement method enables accurate detection of multiple gases based on their infrared absorption characteristics, ensuring stable and interference-resistant gas monitoring.
The analyzer supports simultaneous detection of gases including carbon monoxide (CO), carbon dioxide (CO₂), methane (CH₄), ammonia (NH₃), hydrocarbons (CnHm), sulfur hexafluoride (SF₆), and sulfur dioxide (SO₂). With high measurement accuracy (≤±2% F.S.) and resolution up to 0.01%, the instrument is suitable for applications requiring precise and continuous gas concentration monitoring.
Designed for both industrial process monitoring and environmental gas analysis, the system provides fast response (T90 ≤ 10 seconds) and reliable operation in demanding industrial environments.
