Measurement PrincipleUV-DOAS
Overview
Gasboard-3200UV is a rack-mount biogas analyzer that measures H2S before and after the scrubber by UV-DOAS, with modular CH4, CO2 (NDIR) and O2 (ECD) sensors for continuous monitoring without purge cycles. Dual H2S ranges help verify scrubber efficiency and protect downstream equipment.
Key Features
- UV-DOAS technology to measure H2S, higher accuracy and longer lifetime
- Continuous H2S measurement without purging required.
- Standard 3U rack type enclosure, easy for system integration
- Modular sensor design ensures simple maintenance
- Independent sensor and signal processing for each gas component
- Automatic zeroing with air reduces drift
- Data logging software available to save real time data into external PC, convenient for research use
