Hanna Nitrate Checker

The Hanna Nitrate Checker is a pocket colorimeter for nitrate in saltwater, and it reads 0.0 to 75.0 ppm on a digital display. The high range suits fish-only tanks and reefs with corals that tolerate nitrate of 30 ppm or more. For reefs that need nitrate kept very low, Hanna's HI781 low range checker reads more finely.
