Simple lawn PH tester (Easy way to check PH, Moisture and Sunlight without taking soil samples)

Hi. Wondering how you know the ph meter is accurate? Thanks

it is a little bit of an assumption. The needle moves when i put in the ground so its doing something. remember to use it when the moisture level is not low.
