Abstract Due to the characteristics of long production cycle, short storage cycle and high price of ethanol combustible gas reference material, a dynamic ethanol gas generation device was designed. The device can produce four kinds of ethanol gas with different concentrations, which is easy to carry, simple to operate and high precision. This paper introduces the origin of the device design, device principle, hardware selection, software design. Finally, it was sent to the National Institute of Metrology,China. The calibration experiment is proved that the device meets the requirements.
