The pH test indicator is perfect for easy pH level testing, covering a wide range, from 4.0 to 8.5.
Simply fill the test-tube supplied halfway with nutrient solution, add 3 drops of pH Test Indicator, shake and observe the resulting colour.
Compare with the colour chart to check your pH level.
Very reliable, simple to use and cheap, the pH test kit advantageously replaces the expensive digital pH meters.
Good for a minimum of 200 tests per kit.
