Marine
nitrate low range Checker
The
Hanna Marine Low Range Nitrate Checker® bridges
the gap between simple chemical test kits and professional
instrumentation. Chemical test kits have limited accuracy and resolution
since they rely upon the human eye to discern differences in color.
Professional instrumentation incorporates a light source such as an LED or
tungsten lamp with a filter and a light sensing detector to precisely
determine absorbance and ion concentration. Professional instrumentation
offers greater resolution and accuracy but can cost hundreds of dollars.
The Hanna Marine Nitrate Checker® uses
a fixed wavelength LED and silicon photo detector to provide the accuracy
of professional instrumentation at the affordable price of a chemical test
kit.

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 HI-781 Nitrate Checker HC is a handheld
colorimeter that uses the Beer-Lambert principle to determine the
concentration of nitrate colorimetrically. The HI-781 is designed
specifically to measure low levels of nitrate in a saltwater aquarium. The
0.00 to 5.00 ppm (mg/L) range is ideal for reef aquarium maintenance.
Designed
as a more accurate alternative to chemical test kits, the HI781 provides
quick, accurate results in four easy steps:
Features
-
Easier to use and more accurate than chemical test kits
-
Dedicated to a single parameter
-
Small size, big convenience
-
Ideal for aquariums and marine biology
