Hanna Marine Nitrate Low Range Checker (HI-781)
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 colour. 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.
Hanna Checker | LR Nitrate
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.
- Compact, Portable Design
- Built-in Timer
- 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 colour 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. 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 at-a-glance:
- Easier to use and more accurate than chemical test kits
- Small size, big convenience
- Ideal for aquariums and marine biology
HI782 High Range Nitrate Checker vs HI781 Low Range Nitrate Checker
The HI782 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 at 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 HI781 offers unmatched precision in the measurement of very low levels of nitrate (0.00 to 5.00 ppm). For freshwater samples, Hanna Instruments recommends using the HI97728 Nitrate Portable Photometer.
