Dry chemical detection instrument

The embodiment of the invention discloses a dry chemical detection instrument. The instrument comprises a detection module and a main control board, the detection module is matched with a dry chemical reagent carrier for detection, the dry chemical reagent carrier comprises a diffusion layer, an electrode pair is arranged on the diffusion layer, and a blood sample to be detected is added to the dry chemical reagent carrier; wherein the detection module is used for detecting the sample resistance of a to-be-detected blood sample by using an electrode pair under the condition that the to-be-detected blood sample is distributed on the diffusion layer, and detecting the sample intensity of a reflected light signal of the sample under the condition that the to-be-detected blood sample reacts with a dry chemical reagent solidified in a dry chemical reagent carrier; the sample resistance and the sample intensity are sent to the main control board; and the main control board is used for calculating the sample concent
