How to Choose the Best Soil pH Tester

To prevent your garden from being lackluster, you should check various levels in your soil. One of these is pH. A pH level that is too high means the soil is acidic and too low is alkaline – both are terrible for plants. These meters let you measure these levels easily. We’ve brought you the best rated pH soil tester reviews so you can check out only the best! Here are some things to know.

Battery Powered: Some meters will run on a battery to make sure that you get a great digital reading. Most on this list don’t require a battery or, indeed, any other external power source to function and give you an accurate reading.

Measuring Range: This is the range that the meter will test for. 7 is an optimal pH, while anything more or less is varying degrees of bad for your plants. Keep a close eye on this number for success.

Length: This is the length of the meter, or more accurately, the length of the probe that will test your planting soil. Longer reach deeper down, for deeper rooted plants and possibly more accurate readings.

Multi-Function: Does it just test pH? Most meters will test at least moisture as well, and some on this list also check light intensity based on the position of your flower beds and how much sun it receives during the test.

Display: The display on the meter can either be a needle display, where it hovers over a certain number and you try to get the best guess or a more accurate and true digital display that shows exact numbers.

Warranty: The warranty will ensure that the product is working and is not subject to any mechanical or manufacturing failures. If it does, you can get a full refund or replacement during the time span that is presented.
