Fuji Electric Model ZPAF multigas analyser

Designed to be an integral part of current biomass gasification processes, the Fuji Electric Model ZPAF analyser can provide continuous analysis of important gases produced by biomass fermentation from a wide range of waste products.

Using the time-tested methods of non-dispersive infrared, electrolytic and galvanic measurement principles, the analyser has dual ranges for the gases methane, carbon dioxide, hydrogen sulfide and oxygen.

Ranges for methane and carbon dioxide are 0-20% and 0-100% with a resolution of 0.1% by volume; hydrogen sulfide ranges are 0-500 ppm and 0-2000 ppm, with a resolution of 10 ppm; and oxygen is measured in the ranges of 0-10% and 0-25%, with a resolution of 0.1% by volume. Repeatability is ±0.5% full scale.

The analyser also features automatic zero/span calibration; Modbus and 4-20 mA communication; and many contact outputs.
