Hanna Instruments HI749 Checker Chromium VI Low Range

The Hanna Chromium VI Low Range (0 to 300 ppb) 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 Chromium VI 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.

Details

The HI749 Checker® HC (Handheld Colorimeter) provides a simple, accurate and cost effective way to measure chromium VI. Due to its corrosion-resistant properties, hexavalent chromium plays an important part in the plating industry and cooling towers. However, due to its toxic and carcinogenic nature, chromium VI must be must be sufficiently treated prior to wastewater discharge. 

 

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: Water Quality, Education, Industrial, Municipal Water
