Rather than relying on a probe, it draws a small water sample and performs a genuine colourimetric chemical test on it — the same chemistry a pool shop uses, run continuously and unattended. The reagents are what make that test possible. This is why these units hold water balance more tightly than probe-only systems, and also why they stop working properly the moment the reagent runs low.\u003c\/p\u003e\n\u003ch3\u003eHow Long A Set Lasts\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eApproximately 500-750 tests\u003c\/strong\u003e per set\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e6 to 8 months\u003c\/strong\u003e of water management on a standard residential pool\u003c\/li\u003e\n\u003cli\u003eHeavier bathing loads, longer run times or more frequent test cycles will shorten this\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThose are the manufacturer's figures for typical domestic use.
