| Zusammenfassung: | The utility model discloses a fixed gas alarm detection anti-electric shock calibration cover. The calibration cover comprises a conductive calibration cover body, wherein the body is provided with adetection port, an air inlet hole and an air outlet hole, the detection port is provided with an insulating layer, the body is provided with an induction electricity measurement structure and a contact electricity measurement structure, and when the body is installed on a detection head of a gas alarm, a contact detection head of the contact electricity measurement structure is in contact with a metal shell of the gas alarm. When the anti-electric shock calibration cover is used, when the calibration cover touches a metal shell of the gas alarm, the induction electricity measurement structureand the contact electricity measurement structure send out electricity measurement feedback signals, and if the induction electricity measurement structure measures that electricity exists and the contact electricity measureme |
