These readings give you a combined view of the listed water-quality measures rather than a result for just one parameter. The tester can detect small water changes before they become problems, and a reading beyond a parameter’s range appears as its maximum or minimum value.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003epH: 6.2–8.4\u003c\/li\u003e\n\u003cli\u003eNO3: 0–250 ppm; NO2: 0–20 ppm\u003c\/li\u003e\n\u003cli\u003eCL2: 0–10 ppm; GH: 0–425 ppm; KH: 40–180 ppm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eHow do you use the digital aquarium water tester?\u003c\/h3\u003e\u003cp\u003eUse a test strip and the tester’s “OK” button to get a digital result without interpreting a color chart.
