Nitrate High Range Colorimeter HI782 - Marine Water - Hanna Instruments

Nitrate is a by-product of the Nitrogen cycle. Excessive amounts of nitrates in a reef and fish only aquariums can promote the growth of undesirable organisms including algae and dinoflagellates which can quickly choke out filtration, lighting, and sessile organisms.

The HI782 Nitrate Checker HC by Hanna Instruments is a simple and accurate handheld colorimeter that uses the zinc reduction method to determine nitrate concentration in marine applications. With a digital read out, there is no more struggling to determine colors visually. The HI782`s high range of 0.0 - 75.0 ppm makes it ideal for measuring high nitrate levels found in saltwater aquariums.
