HI-782 MARINE HIGH RANGE NITRATE CHECKER
HI-782
HI-782 Marine Nitrate High Range handheld checker is designed to measure high levels of nitrate in aquariums and marine biology applications.
The HI-782 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 colours visually.
- Measurements with a range up to 75.0ppm
- Less complex laboratory grade accuracy - Requires only 1 reagent
- Simple, intuitive operation (single button)
- Compact and precise whether at home, at work, or on-the-go
Each HI-782 is delivered in a case with custom insert and supplied with:
- Sample cuvette and cap (2 pcs.)
- Marine Nitrate High Range reagent starter kit (reagents for 10 tests)
- 3 mL pipette (1 pc.)
- 1.5V AAA Alkaline battery (1 pc.)
- Instruction manual
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.
HI-782 High Range Nitrate Checker vs HI-781 Low Range Nitrate Checker
The HI-782 was designed to quickly and easily measure nitrate levels for aquarist with higher-than-average nutrient levels.
This includes saltwater aquariums that are fish-only or have corals that can tolerate elevated levels of nitrate up to 30 ppm or more.
Very low levels of nitrate are critical for many saltwater reef aquariums, as nitrate can cause damage and possible death to certain delicate corals and invertebrates. For this reason, the HI-781 offers unmatched precision in the measurement of very low levels of nitrate (0.00 to 5.00 ppm).
