Zusammenfassung: | The present invention relates to a reagent injection device for a residual chlorine concentration measuring instrument for measuring a residual chlorine concentration using an absorption spectrophotometry. The reagent injection device for the residual chlorine concentration measuring instrument comprises: a reagent storage pack which stores a reagent in the form of a liquid and having an injection port disposed at a lower end such that the reagent is injected into the residual chlorine concentration measuring instrument by its own weight, and is made of a shrinkable material according to an amount of storage of the reagent; a pressurizing means for applying a pressure to the reagent storage pack such that the reagent storage pack shrinks as the reagent of the reagent storage pack is exhausted; and a switch for sensing the exhaustion of the reagent by contacting the pressurizing means after the reagent of the reagent storage pack is exhausted.
본 발명은 흡광광도법을 이용하여 잔류염소 농도를 측정하는 잔류염소 농도 측정기에 시약을 주입하는 장치로서, 액체 형태의 시약을 저장하고, 자중에 의해 상기 잔류염소 농도 측정기로 시약이 주입되도록 하단에 주입구가 배치되고, 시약의 저장량에 따라 수축 가능한 재질로 이루어진 시약 저장 팩; 상기 시약 저장 팩의 시약이 소진됨에 따라 상기 시약 저장 팩이 수축되도록 상기 시약 저장 팩에 압력을 가하는 가압 수단; 및 상기 시약 저장 팩의 시약이 소진된 후 상기 가압 수단과 접촉하여 시약의 소진을 감지하는 스위치를 포함하는 잔류염소 농도 측정기용 시약 주입 장치에 관한 것이다. |
