HI781 Marine Nitrate Checker HC Handheld Colorimeter - Hanna Instruments

The HI781 Nitrate Checker HC by Hanna Instruments is a simple and accurate handheld colorimeter that uses the Beer-Lambert principle to determine nitrate concentration. The HI781`s low range of 0.00 - 5.00 makes it ideal for measuring the low nitrate levels found in saltwater aquariums.

Why are Nitrate levels important?
Excess nitrates in a reef system can lead to an overgrowth of undesirable algae and dinoflagellates. Alternatively, not enough nitrates can lead to starvation for SPS and other corals.
