Description:

Hanna Alkalinity Checker is a accurate way to test your Marine Aquarium. Its small and easy to use.

Marine Alkalinity Checker
The Hanna Marine Alkalinity 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.

Professional instrumentation offers greater resolution and accuracy but can cost hundreds of dollars.

The Hanna Marine Alkalinity Checker measures alkalinity in parts per million (ppm) of calcium carbonate (CaCO3) ,using a fixed wavelength LED and silicon photo detector to provide the accuracy of professional instrumentation at the affordable price of a chemical test kit.

Benefits:
  • Compact, Portable Design
  • Built-in Timer
  • One-Button Operation

  • The HI755 Checker HC (Handheld Colorimeter) provides a simple, accurate and cost-effective way to measure alkalinity.

    Crucial in marine environments, alkalinity provides both the carbonate ion required for calcium carbonate skeletal regeneration of coral reefs, as well as a pH buffer against large changes in acidity.

    Designed as a more accurate alternative to chemical test kits, the HI755 provides quick, accurate results in four easy steps:

    Alkalinity, Seawater
