A new static gas analyser for anaerobic digestion (AD) biogas, and landfill gas monitoring suits tight-budget demand with top-quality design, components and engineering. The new GA3000 uses Geotech’s robust, field-proven technology to bring low-cost to automated fixed-position monitoring of methane-rich biogas. Easily operator installed, user field-calibrated and zeroed, the compact, self-contained, single-cabinet GA3000 has gas conditioning as standard. It continuously analyses CH4, CO2, O2 and optionally, H2S at 0-5000ppm. They are measured, at user-set timings, and supply data via three or four, 4-20mA local outputs. Users also set alarm levels and can see screen-displayed readings on a large, clear, backlit display.
