Overview
Gasboard-2205 is a UV-DOAS gas bench using a flashing xenon lamp and multi-reflection long path for high sensitivity, measuring SO2, NO and NO2 at ranges below 100 mg/m³ for ultra-low emission monitoring. One cell handles up to three gases, NO2 is measured directly without a converter, and it is immune to moisture and vibration.
Key Features
- Advanced UV DOAS sensor for Measurement of ultra-low SO2, NO ≤250ppm, the loweat range to be 0-50mg/m3 & Optional NO2
- One chamber for up to 3 gases components measurement simultaneously
- Measurement NO2 directly without converter, and lowest to 100mg/m3
- Automatic temperature compensation
- No moisture & vibration interference
- High precision, good stability and long life
