The methane gas evolved by biological decomposition is accumulated in a plastic bag, and the volume of gas is measured with a monomeric device.
That volumetric measurement attains as precise as 0.1mg accuracy without using any special technique or costly equipment.
(It is well comparable to an ordinary chemical analyzer.)
Six units can be run in parallel
Each of the units is adjusted independently for conditions of temperature and gas flow rate.
If not needed to run all units, just turn off the heater power and close gas collection path valves of unused units.
Space-saving design for compactness
All six units are arranged on a turntable, and the measurement will be carried out in a limited space.
Compact enough to fit on an ordinary experimental deck used for physics and chemistry.(730×610)
Independent temperature control for each unit
Temperature controllers on the operation panel allow independent setting for each unit.
In the same sense, stirring time is independently adjusted by timers provided for each unit on the operation panel.
