How To Find The Best Soil pH Tester?

The trick to find the best soil pH tester depends on your needs. There are tools that can have pH detection, moisture sensor and light sensor. Some have led screen for readability convenience, and certain devices have longer probes for testing soils beyond the plant root. Some are designed to test both soil and liquids. Price is also another important factor. The product that has features befitting your requirement and budget, and also of high quality, durable and easy to maintain is the best pick.

How To Understand The Meter Readings Of The Soil Tester? Is It Too Complex?

The soil tester’s meter readings are not difficult to read when you know what the levels indicate.

  • The pH level 7 is the neutral point.
  • If your soil reading shows anything between 6 - 7.5 then you are approximately close to the neutral level. Hence, your soil is suitable for growing plants, trees, herbs or grasses.
  • Below 7/6.5 pH level is acidic and below 5.0 is very acidic and undoubtedly not suitable for plant growth.
  • If the meter reads 7.5 or above then the soil is alkaline and you cannot grow plants in it.

If your soil is too acidic or alkaline you can directly introduce fertilizers, topsoil, compost etc. and make it suitable for growing beautiful turf, plants or trees.

What Are The Advantages Of Using Soil pH Tester?


The readings displayed on the digital soil pH meter are completely accurate which offers considerable benefits to the user. Any mistaken in readings even by a fraction can lead to a complete lapse in the growth of plants, application of fertilizers and necessary nutrients in the soil. Therefore, accuracy is an advantage that other pH level testers cannot match up to that of a digital meters.

Simplistic Usage

The soil testing device is very easy to use as you only need to poke an end in the soil and get the readings. As soil needs to be tested multiple times at different spots to be sure about the acidity or alkaline level, these digital meters are quite handy and keep hands clean at all times. PH testing stripes and tubes on the other hand are very messy and much more difficult to use.

Precise Results

Unlike other forms of testing soil’s ph level, the digital testers are by far the most precise because of displaying the exact pH level even to the 0.01 pH unit.


ph meters are not like the other soil pH testing methods. This is a huge relief to all those who have trouble reading the color coded testers and distinguishing the lighter shades of the same color. Such color difficulty does not exist if it is a ph meter.

Multiples Usage

The ph meter is not a one-time-use product. You can use it as many times as you want, unlike other pH testing kits which must be disposed of after one use.


The device is very small in size and you can conveniently carry them with you in your pocket to test the soil in a farmland, a friend’s yard and so on.

Any Limitations Of The pH Soil Testing Device Should I Be Aware Of?

  • While the meter is portable and easy to use, its readings can be inaccurate in intense climatic conditions.
  • Electronic soil testers are costlier than the manual testing kits (colored dyes or ph test strips)
  • You can only continue to use them again when you calibrate the device at regular intervals.

Things To Take Care Of While Using The pH Soil Testers

To maintain the accuracy of the digital tester, it would work best if you regulate every time before testing the soil. In terms of batteries, many soil test kits do not need batteries or plugs. Others come with in-built batteries. Since soil testing doesn’t consume too much battery per use; they usually last for a very long period.

Best Soil pH Tester - Winner

These are my top 5 picks out of the many ph testing meters available in the market. My personal favorite is Covery’s 3 in 1 Soil Tester. Plants survive on 3 elements: light, water and soil nutrients. With this single tool, i can test all three elements, which makes it the best soil pH meter in my opinion.

I also need a longer probe. When juggling between Covery’s 3 in 1 soil tester and Gain Express’s Soil pH & Moisture Meter, I found that the later didn’t show accurate results.

To dig deeper, the soil had to be moistened quite a bit or else forcing the probe could damage it. Ultimately, Covery’s 3 in 1 shows more precise results which undoubtedly becomes my favorite tool.

Dr. Lyn Premium Digital pH Pen Tester is an excellent choice for those who need a soil and water testing device. Because Dr. Lyn Premium Digital pH Pen Tester needs 4 batteries to function and my sole purpose is testing soil, I went ahead with Covery’s 3 in 1. And, since it doesn’t need any batteries, it saves me extra bucks for long term use.

Finally, out of all the 5 products listed, Covery’s 3 in 1 is the least priced while it shows very precise ph level readings with moisture and light sensors as an added bonus.
