A simple and economical way to measure the pH of your nutrient reservoir or watering can. The kit gives a visual indication of the pH of water between a range of 5.6-7.4 and contains enough for around 150 tests.
To use simply fill the supplied tube with your water you wish to test, add a couple of drops of the reagent liquid to it and shake. The water will change colour according to it's pH. You can then compare the colour to the supplied chart to get an indication of the pH of your water.
For a more accurate means of pH testing we highly recommend using a pH meter.
