description The invention discloses an electric shock-resistant calibration cover for detection of a fixed gas alarm. The calibration cover comprises a conductive calibration cover body, wherein the body is provided with a detection port, an air inlet hole and an air outlet hole; the detection port is provided with an insulation layer; and the body is provided with an induction electrical measurement structure and a contact electrical measurement structure. When the body is mounted on a detection head of a gas alarm, a contact detection head of the contact electrical measurement structure is in contact with a metal shell of the gas alarm. With the adoption of the electric shock-resistant calibration cover, when the calibration cover touches the metal shell of the gas alarm in use, the induction electrical measurement structure and the contact electrical measurement structure send out electrical measurement feedback signals; if electricity is measured by the induction electrical measurement structure but no electricity is
