It is built for South African fishkeepers and reef hobbyists who want a precise, easy-to-read phosphate result without guessing at colour charts. Clear digital digits take the uncertainty out of testing, which helps anyone with poor eyesight or difficulty telling subtle colour changes apart.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eKey Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDigital accuracy instead of colour matching:\u003c\/strong\u003e Large, easy-to-read digits replace the shade comparisons used in traditional chemical test kits.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow-range sensitivity:\u003c\/strong\u003e Measures phosphate from 0.00 to 2.50 ppm (mg\/L) at a resolution of 0.01 ppm (mg\/L) across 250 points.

It is a low-range checker intended for the lower phosphate concentrations typical of well-maintained freshwater and marine aquariums.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan I use the HI713 on both my reef tank and my freshwater aquarium?\u003c\/strong\u003e\u003cbr\u003e\nYes. The HI713 is suitable for both freshwater and marine aquariums, so one checker covers both setups.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow many tests do I get, and what do I need for refills?\u003c\/strong\u003e\u003cbr\u003e\nThe checker comes with 6x HI713 reagent packets.
