The General Hydroponics pH Test Kit measures the pH level of your hydroponics nutrient solution.
It gives you a reading on a scale from 4.0 to 8.5 pH units.
You use only 3 drops of the pH Test Indicator solution per testing so it goes a long way!
The color comparison chart is printed right on the label of the 1 ounce bottle of indicator solution so it cannot get misplaced. Enough solution for about 200 tests.
The General Hydroponics pH Test Kit is easy to use and gives you fast results.
