Saltwater Nitrate High Range Checker® HC - HI782
The HI782 Marine Nitrate High Range Colorimeter is specifically designed to quickly and accurately determine high levels of nitrate for saltwater aquariums and marine applications. With a digital read out, there is no more struggling to determine colors visually.
- Measurements with a range up to 75.0 ppm
- Less complex laboratory grade accuracy = Requires only 1 reagent
- Simple, intuitive digital operation
- Compact and precise whether at home, at work, or on-the-go
Nitrate is the final step in the Nitrogen cycle. Excessive amounts of nitrates in saltwater aquariums facilitate the growth of undesirable organisms such as algae and dinoflagellates.
The HI-782 Nitrate Checker HC uses the Zinc Reduction method, a no filter process, to measure the concentration of nitrate colorimetrically, ultimately reducing the time of each test and leaving no additional waste.
With higher range measurements, such as the HI-782 which ranges from 0.0 up to 75.0 ppm (as NO3–), there is also no dilution procedure needed.
Features at-a-glance:
- For use with saltwater samples.
- More accurate than chemical test kits.
- Dedicated to a single parameter.
- Small size, big convenience.
- No errors with a digital readout.
- Ideal for aquariums and marine biology applications.
