Description

The nitrogen cycle comes to an end with nitrate. Nitrate levels that are too high encourage the growth of unwanted organisms like algae and dinoflagellates in saltwater aquariums. Using the HI782 Nitrate Checker HC, you can easily, precisely, and affordably measure nitrate in your saltwater aquarium from 0.0 to 75.0 ppm (as NO3-).

Using the Zinc Reduction method, a no filter process, The HI782 Nitrate Checker HC measures the concentration of nitrate colormetrically.  Hanna Instruments Checker HC provides quick results in four easy steps:

HI782 High Range Nitrate Checker vs HI781 Low Range Nitrate Checker

For aquarists with higher-than-average nutrient levels, the HI782 was developed to swiftly and easily monitor nitrate levels. This includes saltwater aquariums that only contain fish or corals that can withstand excessive nitrate levels of 30 ppm or higher.
Many saltwater reef aquariums require very low nitrate levels because nitrate can harm and even kill some sensitive corals and animals. This is why the HI781 offers unparalleled precision in the assessment of extremely low nitrate levels (0.00 to 5.00 ppm). Hanna Instruments advises using the HI97728 Nitrate Portable Photometer for freshwater samples.
