The precision digital gas mixer is a universal, mobile apparatus capable of adjusting the required mixture of the gas, selected by the user, with air. The apparatus is completely automatic, requiring only the connection of the selected gas, the air and the electric power.The mixing process is of totally closed system. When the specified input pressures resp. the possible minimum differential pressure are set, the mixture will be produced independently of the ambient pressure. Due to the closed system mixing, neither the ambient temperature nor the moisture content will influence the produced mixture. The mixing unit does not require oil lubrication.
Accuracy of the mixing apparatus is ± 0.1vol.%,. In the whole range 1 – 99 Vol.% can be changed the necessary gas-air mixture without any additional apparatus. Technical parameters:- Computer controlled automatic apparatus. - Controlling: keyboard, mouse - Gas/air mixing range: 1- 99 Vol.% 0,1 vol.%- Inlet pressure:gas inlet – appr. 1 barair inlet – appr. 1 bar- Quantity of the delivered gas/air mixture: 1-99 Vol. % 233 l/h-86 l/h- Mains supply:230 VAC / 50 Hz
Thus no oil vapour will get into the mixture that would settle onto the cadmium disc of the spark test apparatus resp. into the gap of the MESG apparatus, that would make measuring impossible.
