Claim Text:
1. A detector for detecting sodium hypochlorite concentration, comprising: a first electrode and a second electrode disposed opposite the first electrode, the first electrode and the second electrode being soaked in a sodium hypochlorite solution under detection, wherein an electrical path is formed among the first electrode, the sodium hypochlorite solution and the second electrode; a housing, accommodating the first electrode and the second electrode; the first electrode comprising a first detecting portion exposing outside the housing and extending outward from the housing, and the second electrode comprising a second detecting portion exposing outside the housing and extending outward from the housing; the housing comprising a first outer wall disposed at one side of the first detecting portion away from the second detecting portion, a second outer wall disposed at one side of the second detecting portion away from the first detecting portion, and a measurement space formed between the first outer wall and the second outer wall and separating the first detecting portion from the second detecting portion; the first outer wall being formed at a height greater than that of the first detecting portion, and the second outer wall being formed at a height greater than that of the second detecting portion; the electrical path being located in the measurement space; and a processing unit, electrically connected to the first electrode and the second electrode, configured to measure a plurality of ions in the sodium hypochlorite solution in the electrical path to obtain a conductivity of the sodium hypochlorite solution and to accordingly calculate the sodium hypochlorite concentration of the sodium hypochlorite solution.
