Excessive amounts of nitrates in saltwater aquariums facilitate the growth of undesirable organisms such as algae and dinoflagellates. The HI782 is a simple, accurate, and cost-effective way to measure nitrate from 0.0 to 75.0 ppm (as NO3–) in your saltwater aquarium.\u003c\/div\u003e\r\n\u003cdiv\u003e\r\n\t \u003c\/div\u003e\r\n\u003cdiv\u003e\r\n\tThe HI782 Nitrate Checker HC uses the Zinc Reduction method to measure the concentration of nitrate colorimetrically.

This includes saltwater aquariums that are fish-only or have corals that can tolerate elevated levels of nitrate at 30 ppm or more.\u003c\/div\u003e\r\n\u003cdiv\u003e\r\n\t \u003c\/div\u003e\r\n\u003cdiv\u003e\r\n\tVery low levels of nitrate are critical for many saltwater reef aquariums, as nitrate can cause damage and possible death to certain delicate corals and invertebrates. For this reason, the HI781 offers unmatched precision in the measurement of very low levels of nitrate (0.00 to 5.00 ppm). For freshwater samples, Hanna Instruments recommends using the HI97728 Nitrate Portable Photometer.\u003c\/div\u003e\r\n\u003cdiv\u003e\r\n\t \u003c\/div\u003e\r\n\u003cdiv\u003e\r\n\t\u003cdiv\u003e\r\n\t\tSKU\u003cspan style=\"white-space:pre\"\u003e \u003c\/span\u003eHI782\u003c\/div\u003e\r\n\t\u003cdiv\u003e\r\n\t\tRange\u003cspan style=\"white-space:pre\"\u003e \u003c\/span\u003e0.0 to 75.0 ppm (as NO3–)\u003c\/div\u003e\r\n\t\u003cdiv\u003e\r\n\t\t0.0 to 50.0 ppm (calculated) using dilution\u003c\/div\u003e\r\n\t\u003cdiv\u003e\r\n\t\tResolution\u003cspan style=\"white-space:pre\"\u003e \u003c\/span\u003e0.1 ppm\u003c\/div\u003e\r\n\t\u003cdiv\u003e\r\n\t\tAccuracy @ 25°C\/77°F\u003cspan style=\"white-space:pre\"\u003e \u003c\/span\u003e±2.0 ppm ±5% of reading @ 25 °C (77 °F)\u003c\/div\u003e\r\n\t\u003cdiv\u003e\r\n\t\tLight Source\u003cspan style=\"white-space:pre\"\u003e \u003c\/span\u003eLED @ 525 nm\u003c\/div\u003e\r\n\t\u003cdiv\u003e\r\n\t\tLight Detector\u003cspan style=\"white-space:pre\"\u003e \u003c\/span\u003esilicon photocell\u003c\/div\u003e\r\n\t\u003cdiv\u003e\r\n\t\tMethod\u003cspan style=\"white-space:pre\"\u003e \u003c\/span\u003eZinc reduction method.
