Biogas analyzer Gasboard-3200UV

hydrogen sulfideCO2/02CO

Introduction Gasboard-3200UV is the new generation rack type biogas analyzer that primarily designed based on UV-DOAS technology to measure H2S concentration precisely before and after H2S scrubber, and extended with modular sensor of CH4(NDIR), CO2(NDIR) and O2(ECD) to realize online continuously monitoring of biogas quality without purging cycle required.The dual measurement ranges of UV-H2S detector makes it very suitable to be used to monitor H2S concentration difference before and after scrubber. It provides an ideal solution to guarantee the H2S scrubber efficiency, protect downstream expensive equipment from the damage of overload H2S, minimize the investment for users and optimize the biogas monitoring process. 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 Specifications Measurement Gases: H2S/CH4/CO2/O2 Technology: H2S: UV-DOAS; CH4/CO2: NDIR; O2: ECD Measurement Range: H2S: 0-500/5000ppm; CH4:0-100%; CO2:0-50%; O2:0-25% Accuracy: ±2%F.S. Resolution: H2S: 1ppm; CH4: 0.01%; CO2: 0.01%; O2: 0.01% Repeatability: ≤2% Response time: T90＜60s Warm-up time: 800s Inlet flow: (0.7~1.2) L/min Output: RS485/RS232, (4-20)mA Power supply: 220V AC, 100W
