The invention relates to the field of electrochemical sensors, in particular to a visual detection method of a solid contact type ion selective electrode. The ion activity (concentration) of the solid contact type ion selective electrode and the color change of the electrochromic material are utilized to construct a system, and the potential signal of the ion selective electrode is indicated by the electrochromic material in the electrochromic device, so that the visual determination of ions is realized. Compared with a potential readout signal, the visual detection method of the solid contact type ion selective electrode does not need the design of related circuits or line connection of the A/D analog-to-digital converter, and has the advantages of simplicity, rapidness, intuition, low energy consumption and the like.
