The HI781 Marine Nitrate Low Range Colorimeter is designed to accurately determine low range nitrate levels in saltwater aquariums and marine applications.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
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 Nitrate Checker HC is a handheld colorimeter that uses the Beer-Lambert principle to determine the concentration of nitrate colorimetrically. 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.
For samples containing 5-50 ppm nitrate, follow the dilution procedure.
I purchased 2 of these lights to go on a 40 long tank and I like the look of the lights sitting above overhead the tank.
Of course they have 2 settings one which is a soft blue for evening.
The quality and price have pleased me too.
