Nitrate is the last step in the nitrogen cycle. Excessive amounts of nitrates in saltwater aquariums facilitate the growth of undesirable organisms such as algae and dinoflagellates. The HI782 is a simple, accurate, and cost-effective way to measure nitrate from 0.0 to 75.0 ppm (as NO3-) in your saltwater aquarium.
The HI782 Nitrate Checker HC uses the zinc reduction method to measure nitrate concentration colorimetrically. The HI782 provides fast, accurate results in four easy steps:
Technical characteristics :
- For use with salt water samples.
- More accurate than chemical test kits.
- Dedicated to a single parameter.
- Small size, big convenience.
- No errors thanks to the digital display.
- Ideal for aquariums and marine biology applications
HI782 High Range Nitrate Checker vs. HI781 Low Range Nitrate Checker
The HI782 was designed to quickly and easily measure nitrate levels for aquarists with higher than average nutrient levels. This includes saltwater aquariums that only contain fish or corals that can tolerate high nitrate levels at 30 ppm or more.
Very low nitrate levels are essential for many saltwater reef aquariums, as nitrate can cause damage and possible death to some delicate corals and invertebrates. For this reason, the HI781 offers unparalleled accuracy in measuring very low nitrate levels (0.00 to 5.00 ppm). For freshwater samples, Hanna Instruments recommends using the HI97728 Portable Nitrate Photometer.
