Iron Low Range Checker® HC - HI746
£
-
The Hanna Iron 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 absorbance and ion concentration. Professional instrumentation offers greater resolution and accuracy but can cost hundreds of dollars. The Hanna Iron 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.

Copper Low Range Checker® HC
£
-
The Hanna Checker® bridges the gap between simple chemical test kits and professional instrumentation. Chemical test kits are not very accurate and only give 5 to 10 points resolution while professional instrumentation can cost hundreds of dollars and can be time consuming to calibrate and maintain. The Checker® is both accurate and affordable.
Chromium VI Low Range Checker/Tester - HI749
£
-
The Hanna Chromium 6 Low Range Checker (HI749) tests for the presence of Chromium 6 (Hexavalent Chromium) in concentrations within the range of 0 to 300 ppb with an accuracy of ±3 ppb in samples such as drinking water and wastewater. With a digital readout, Hanna Checkers provide greater measurement accuracy when compared with chemical test kits that rely on human perception of color.

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® 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.
