Hanna Marine Nitrate checker HI 781
Hannas nya nitrate checker.
With a digital read out, there is no more struggling to determine colors visually.
- Range: 0.00 to 5.00 ppm (as NO3–) [0.0 to 50.0 ppm (calculated) using dilution]
- Built-in timer so you don't miss a step.
- Saltwater Compatible
For samples containing 5.0 to 50.0 ppm nitrate, follow the approved dilution procedure.
Nitrate is a by-product of the Nitrogen cycle. Excessive amounts of nitrates in a reef aquarium can promote the growth of undesirable organisms including algae and dinoflagellates while insufficient amounts can lead to starvation in which SPS and other corals will show signs including the loss of color and paleness.
The HI781 is designed specifically to measure low levels of nitrate in a saltwater aquarium.
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.
