The HI-779 is a checker photometer with which you can quickly, easily, and moreover, accurately measure pH in swimming water according to the recognised phenol red method. The checker does not have to be calibrated with buffers, as with a tester, and there is also no electrode to be stored in storage solution.\u003c\/p\u003e\n\u003cp\u003eDesigned to accurately determine pH levels in pool water using normal disinfectants or salt water chlorination by electrolysis, each HI-779 is delivered in a case with custom insert and is supplied with:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSwimming pool pH reagent starter kit\u003c\/li\u003e\n\u003cli\u003e1.5V AAA Alkaline battery (1 pc.)\u003c\/li\u003e\n\u003cli\u003eInstruction manual\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThis checker is designed as a more accurate alternative to chemical test kits.\u003c\/p\u003e\n\u003cp\u003eHI-779 features a single-button operation system and is easy to use.
