Gasboard-3200L Biomethane Analyzer uses TDLAS, NDIR, and ECD sensors for precise, real-time measurement of CH4, H2S, CO2, and O2 in biomethane. Gasboard-3200L calculates calorific value automatically, making it ideal for biogas quality monitoring, process control, and grid injection.
Gasboard-3200L Biomethane Analyzer is a portable biogas analysis device developed using advanced TDLAS, NDIR, and ECD gas sensing technologies. It is specially designed for biomethane quality monitoring, enabling real-time and precise measurement of CH4, H2S, CO2, and O2. With ultra-low H₂S detection (0–20 ppm) and high-accuracy CH4 readings (better than 0.5% FS), it provides automatic calorific value calculation for use in biogas upgrading, process control, and grid injection.
This analyzer delivers fast results without sample preparation, offering a cost-effective alternative to gas chromatography (GC). Its compact and rugged design makes it ideal for on-site biomethane testing, combining portability, efficiency, and high precision in one device.
Highly selective TDLAS technology for accurate CH4 measurement (<0.5% FS)
Accurately measures hydrogen sulfide from 0–20 ppm, ideal for biomethane quality control
Rapid results, no sample preparation, outperforms GC efficiency
Minimizes consumables and maintenance, offering a reliable and economical solution
