It's an inexpensive meter that is not very accurate. It's fine for an outdoor vegetable garden to get a rough estimate of the soil pH but even then there are better methods. The best way to check pH in soil is with a slurry test and a decent meter. It's the most accurate method. Some people test runoff which is not accurate at all. But if you're growing in soil you don't really need a ph meter.
