774 Checker The HI774 Ultra Low Range Phosphate Checker HC (Handheld Colorimeter) provides a simple, accurate and cost-effective way to measure phosphate in marine systems including reef tanks.

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