Description Overview GAOTek’s Advanced Gas Analysis System with UV DOAS & Multi-Gas Detection is an advanced emissions monitoring solution designed for industrial applications like boiler exhaust, pollution sources, and high-humidity/temperature gas analysis. It employs UV DOAS, IR, electrochemical, and laser technologies to measure up to 50 gas components (e.g., SO₂, NOₓ, CO, H₂S) with high accuracy, minimal drift, and no cross-interference. The system offers real-time data via a 7-inch touchscreen, supports wireless data transfer, and operates in harsh conditions, 14°F to 104°F (-10°C to 40°C). With interfaces like 4 mA to 20 mA, RS485/ModBus, and relay outputs, it’s ideal for continuous emission monitoring in compliance with environmental regulations. Features Detects SO₂, NO, NO₂ with low limits: 0.621 µg/ft³ (49.213 ft optical path) [1 mg/m³ (15 m optical path)] UV technology avoids moisture/dust interference Multi-gas detection: NO and NO₂ can be measured at the same time, without cross-interference or a converter DOAS PLS technology, minimum zero drift and span drift Modular design No moving optical parts; resistant to vibration Available version with external UV bench for use with toxic or corrosive gases. Spectrum automatic adjustment technology; light source adopts to the pulse source Technical Specifications Measurable Gases Nitric Oxide (NO), Nitrogen Dioxide (NO₂), Sulfur Dioxide (SO₂), Oxygen (O₂), Carbon Monoxide (CO), Ammonia (NH₃), Chlorine (Cl₂), Hydrogen Sulphide (H₂S), Etc.
