Terra Aquatica pH Test Kit

Your digital meter will benefit from having a backup in the form of our liquid pH tester, which makes testing extremely simple. Our kit provides up to 500 tests with only 30 ml of liquid and covers a wide range of values, from 4.0 to 8.5.

DIRECTIONS FOR USE:
To read your pH level, all you need to do is add nutrient solution up to the halfway point of the test tube that was provided, add two drops of the pH Test indicator, shake the tube, and then compare the color that was produced to the chart.
