The HANNA® Wide Range Silica Photometer is positioned between simple chemical test kits and advanced professional instruments. Unlike chemical kits, which rely on visual observation to assess color changes, offering limited accuracy and resolution, professional instruments use light sources such as LED or tungsten lamps combined with a filter and light detector to accurately measure ion concentrations. While these professional instruments are highly accurate, their cost can be several hundred dollars. The HANNA® Wide Range Silica Photometer incorporates a silicon photoelectric detector and a fixed wavelength, combining the accuracy of a professional instrument with an affordable cost comparable to a chemical test kit.

Simply measure your samples in a few steps

  1. Take a water sample and insert the cuvette into the photometer
  2. Make a blank
  3. Add the reagent to your solution
  4. Insert the cuvette into the photometer, press the button and read the result

Presentation

HI7134 comes with 2 measuring cuvettes and their cap, reagents for 6 tests and the battery.
