Product Description

    Details

    The Hanna Marine Alkalinity (dKH) 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. This level of instrumentation also 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.

      I received my Hanna Alkalinity Checker and right out of the box it met my expectations. A compact electronic tester to take the guesswork out of different colour hues was exactly what I wanted. I also order an additional reagent which is a good value once you have the original checker.

      Unfortunately my checker had an issue surrounding a bad battery error. I contacted J&L Aquatics who immediately followed up and provided me a contact for the Hanna Canada. After speaking to Hanna Canada the wonderful folks at J&L Aquatics were in constant communication and made sure I got a new checker within the week. A+ service by J&L Aquatics and someone who actually stands by warranty of a product. (Posted on 5/20/2017)
