It provides a digital reading, eliminating the need to visually interpret colour changes from traditional chlorine test kits. The HI701 uses an adaptation of USEPA Method 330.5 and the DPD method, with the reaction producing a pink colour that is measured electronically by the instrument. \u003cspan class=\"contents\"\u003e\u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cspan class=\"PDq2pG_selectionAnchor\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eWith a measuring range of 0.00 to 2.50 ppm (mg\/L) and a resolution of 0.01 ppm, the HI701 is well suited to routine water quality monitoring.
