pHDetector

The pHDetector is able to determine the pH value of an indicator-containing coloured solution fast with decimal precision. First you have to choose which indicator you would like to use, then focuse on a homogeneous part of the solution - possibly in front of white background, in artifical white light - and just read the pH value.

Now five indicators cover the pH interval from 3,1 to 10,3, which are the followings:

Methyl orange: 3,1 - 4,4
Methy red: 4,4 - 6,2
Bromothymol blue: 6,2 - 7,6
Phenol red: 6,4 - 8,0
Phenoltalein: 8,3 - 10,3

The language of the app is the same as the language of your phone (English, German or Hungarian, if something else it's automatically English).
