Silica Low Range Checker® HC - HI705

The Hanna Silica 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 Silica 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 HI705 Checker® HC (Handheld Colorimeter) provides a simple, accurate and cost effective way to measure silica. Silica is found in all natural waters in the dissolved form. Due to the potential to cause scaling, it is undesirable and therefore monitored in industrial applications, and in heating and reverse osmosis systems. Designed as a more accurate alternative to chemical test kits, the HI705 provides quick, accurate results in four easy steps

 

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, Environmental, Education, Pool and Spa
