To easily determine the acidity of your solutions, we developed pH liquid indicator sold in pack. Depending on the pH value of your solution (value between 4.0 and 8.0, you will have to adjust your solution either with sulphuric acid (pH -) or sodium carbonate (pH +). For a use in hydroponic farming and as a transparent aqueous solution testing, it is recommended to obtain a pH value between 5.5 and 6.5. Included in the pack: a 30 ml bottle of reactive solution (~ 200 tests), a colour scale and an empty flask with cap to make the tests
- A 30 ml bottle of reactive solution (about 200 tests) with a colour scale
- An empty flask for testing
- The measurement is calibrated every 0.5 or 1.0 pH unit from 4.0 to 8.0.
- The reagent paper reacts by colorimetric method; the results obtained must be compared to the colorimetric scale given in each box.
