Hanna HI 782 nitrate high range

Hanna Checker - Nitrate HR (NO3) Colorimeter

The HI782 Nitrate Checker HC by Hanna Instruments is a simple and accurate handheld colorimeter that uses the zinc reduction method to determine nitrateconcentration in marine applications.

The HI782`s high range of 0.0 - 75.0ppm makes it ideal for measuring the high 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.

Features

• Designed to accurately determine nitrate levels in aquariums and marine biology applications
• Only requires 1 reagent for simplicity
• No filter process
• Measures with a range up to 75.0ppm
• Easier to use and more accurate than chemical test kits
• Dedicated to a single parameter
• Simple one-button operation
• Large LCD digital read out for added convenience
• Auto shut-off to assure the battery wont be drained
• Compact size for easy travel and storage

The HI782 Checker is a simple, accurate, and cost-effective way to measure nitrate in your saltwater aquarium.

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.
