DETECTION PLATE HAVING IDENTIFICATION INFORMATION AND ANALYZER FOR READING IDENTIFICATION INFORMATION AND IDENTIFICATION METHOD THEREFOR

A detection device having identification information, an analyzer for reading the identification information and an identification method therefor. The detection device includes an upper plate and a bottom plate, which are assembled together to form the housing of the detection device. An identification element (15) for identifying the type of the detection device is disposed on the housing, and the identification element (15) includes at least one identification area, on which at least one recessed portion (152) or one non-recessed portion (151) is disposed. Through cooperation of the identification element (15) disposed on the detection device and a detection switch on the analyzer, i.e., through whether the detection switch of the analyzer is triggered by the identification element (15) or not, the analyzer generates a signal corresponding to whether the corresponding signal is triggered or not to identify the type of the detection device, and the analyzer can automatically identify the type of the detection device in use without the need of selecting the type of the detection device by the user.
