pH Liquid Test Kit



$7.50  $6.75 Save: 10% off
General Hydroponics pH Test Kits make pH testing easy. Simply fill a test-tube halfway with nutrient, add a few drops of pH Test Indicator, and observe the coloration of the liquid in the test vial. Many experienced growers prefer our pH Test Kit to expensive electronic meters because of its reliability and ease of use, which are important factors when the health of a valuable crop is at stake. Use 3 drops per 5mL of solution.

If you think your electronic meter may be malfunctioning, or you don't own one these are great to have on hand. It is also nice for out in the field they are small and fit easily in your pocket. I cheat and use a smaller amount of sample which lets me use a smaller amount of indicator solution to make this last even longer....

for the price I think this is the best low cost option to test pH. Low tech but it doesn't require calibration or batteries ;)
