Review on Hanna Instruments HI701 Handheld Colorimeter by Byron Forman

Revainrating 5 out of 5

Simple and effective test

Compared to the HI 729 fluoride test, this one is very simple. Before adding a reagent, zero the instrument with a water sample. After zeroing, add the powdered reagent, shake for 20 seconds, and then wait two minutes and thirty seconds to get the test result.

Pros
  • Colorimeter
Cons
  • Some errors
