The product is really handy to keep the Ph and EC levels steady in my nutrient solution and the multiple readings can be taken in a row which is really handy. The Ph tester even comes with different packages of Ph buffer solution so that's really handy as well. My plants in my hydroponics system are doing great right now thanks to this product.
