摘要： A corrosive gas detecting sensor has a cartridge, a sensor body, and a connecting unit. The cartridge has a sensor element and a memory device. The sensor element changes its characteristic property when the sensor element contacts a corrosive gas, and the memory stores an initial value of the characteristic property of the sensor element. The sensor body has a control unit which detects a change of the characteristic property of the sensor element when the cartridge is connected to the body and outputs an indication of a fire when a rate of the change exceeding a preset reference value, the cartridge is detachably attached to the sensor body. The connecting unit electrically connects the cartridge with the sensor body when the cartridge is attached to the sensor body.
