The embodiment of the invention discloses a standard gas distribution meter, which comprises a background gas opening, a measuring range gas opening and two flow rate controllers, wherein the two flow rate controllers respectively correspond to the background gas opening and the measuring range gas opening, and in addition, the standard gas distribution meter also comprises a heat insulation layer, a setting unit, a micro control unit (MCU) and a temperature control unit. During standard gas distribution, the flow rate controllers, pipelines connected between the background gas opening and the flow rate controllers and pipelines connected between the measuring range gas opening and the flow rate controllers are arranged in the heat insulation layer, and the temperature in the heat insulation layer is always kept at the constant temperature through the temperature control unit, so the flow rate controllers and the gas flowing into the flow rate controllers are stably kept at a certain temperature, and the external environment interference is avoided.
