The invention discloses a device and method for checking SF6 gas leakage monitoring and alarming apparatuses. The device comprises precise electronic mass flow meters, solenoids, an air pump, a pressure controller, a quick connector, rotor flow meters, a control unit, a human-computer interface, a flow control valve and a connecting pipe. The high-concentration SF6 standard gas and air are mixed by the electronic mass flow meters and are diluted into the required SF6 standard gas with different concentrations and oxygen so as to achieve the requirements for accuracy and repeatability of detection of the monitoring and alarming apparatuses for checking the SF6 gas leakage. The device of the invention can avoid carrying plenty of steel cylinders for SF6 standard gases and diluent gases, has the characteristics of simpleness, rapidness, accuracy and high degree of automation and provides great convenience for checking the SF6 gas leakage monitoring and alarming apparatuses on site.
