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 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 Alkalinity 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.*To zero 1 ml of reagent A is added to deionized/distilled water as a blank.

Features at-a-glance:

  • Easier to use and more accurate than chemical test kits
  • Dedicated to a single parameter
  • Small size, big convenience
  • Ideal for: Aquaculture, Water Quality, Environmental, Education
HI755 Checker® is supplied with (2) sample cuvettes with caps, alkalinity reagent starter kit for 25 tests (1 bottle of alkalinity reagent), 1 ml syringe and tip), ­­­ battery, instructions and quick start guide.

  1. This is a great product and is as easy as it comes Review by Manateemark
    Product Rating:

    I especially like this hanna checker because there is no waiting for the reading to happen. I can easily test the alkalinity of my saltwater aquarium in about 30 seconds using this test kit. My only complaint was that I bought this test kit when it came out so I was not about to get it in DKH, but that does give me a higher amount of testing accuracy as the DKH version would say 9.2, but this ppm version would tell you 164 so you are more easily able to track small changes in alkalinity.
