Fixed Infrared Gas Analyzer LB-36FIA

Fixed Infrared Gas Analyzer LB-36FIA

Fixed Infrared Gas Analyzer LB-36FIA offers precise and reliable measurement of critical industrial gases, including NOx, SO₂, CO, CO₂, CH₄, and H₂S. It operates within a temperature range of -10°C to 45°C and supports a gas flow rate between 500 to 1000 ml/min. It utilizes advanced NDIR technology to deliver fast, repeatable readings. The analyzer features a narrow-band gas chamber absorber for accurate and interference-resistant gas detection.
