Upgrade from chemical test kits to professional instrumentation without breaking your budget. Hanna Instruments Phosphate Low Range Checker HC is a budget-friendly single parameter electronic tester for measuring phosphate levels in freshwater or marine aquariums. Compact handheld colorimeter delivers the accuracy of professional instrumentation at the affordable price of a chemical test kit.

Easier to use and more accurate than chemical test kits, Hanna Instruments Phosphate Low Range Checker HC provides a simple cost effective way to detect even low levels of aquarium phosphate. Routine phosphate level measurement is crucial to maintain high aquarium water quality with low levels of the algal nutrient phosphate.

Hanna Instruments Phosphate Low Range Checker HC measures just 2.4" x 1.5" x 3.2" high and features a range between 0 to 2.50 ppm with 0.01 ppm resolution (±0.04 ppm ±4% accuracy @ 25°C/77°F of reading).

Hanna Instruments Phosphate Low Range Checker HC (HI713) is supplied with (2) sample cuvettes with caps, phosphate LR reagent starter kit for 6 tests (6 powder reagent packets), 1.5V AAA battery, instructions and quick start guide.

General Information
The Hanna Phosphate Low Range Checker HC 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 ion concentration. Professional instrumentation offers greater resolution and accuracy but can cost hundreds of dollars. The Hanna Phosphate Low Range Checker HC 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.
