Overview
KSA-2100UV is a biogas analyzer using UV absorption spectroscopy (UV-DOAS) and NDIR sensor technology to measure the main biogas components CH4, CO2, H2S and O2.
UV-DOAS technology provides stable analysis even at high H2S concentrations, and the design minimizes biogas loss during measurement.
It supports a 7-inch touch screen, real-time gas concentration monitoring and RS-232/RS-485 communication, and is used for process control and quality control at anaerobic digesters, landfill gas sites and biogas plants.
Key Features
- Simultaneous measurement of 4 gases: CH4, CO2, H2S, O2
- High-concentration H2S measurement using UV-DOAS
- NDIR and electrochemical (ECD) sensors
- High accuracy and reliability with UV-DOAS technology
- Stable gas analysis even at high H2S concentrations
- Designed to minimize biogas loss during measurement
- 7-inch touch-screen LCD display
- Real-time gas concentration monitoring
- 4~20 mA analog output
- RS-232/RS-485 communication
- Continuous monitoring for optimized process control
- Modular design for easy calibration
- Automatic zero function
- Analysis system suited to biogas production and treatment facilities
