Best Soil pH Meter: The Top Product Review For You

In the event that you have a passion for gardening, or even if you keep a garden for some other reason, understanding the soil pH is one of the most important things you will need to do. To help you with this, you need the best soil pH meter. There is quite a number of these in the market, and it would be a brilliant idea for you to ensure you choose the best of them.

As long as you have the basic chemistry knowledge, you should know what pH is all about. This is simply a measure of the basicity or the level of acidity in the soil. The pH scale runs from 1 – 14, with a neutral at 7. Water is neither basic nor acidic, hence it is neutral at a pH of 7. Anything with a pH level lower than 7 is acidic, while any substance whose pH measures above 7 are basic.

With respect to gardening, the pH value of the soil is really important. The reason for this is because the soil plays an important role in the growth of the plants you desire. These plants will rely a great deal on the nutrients in the soil to thrive, so by testing the pH level of the soil sample, you are simply determining whether the soil is healthy enough for your plants to grow and thrive.

Why You Should Trust Us

We have a passion for gardening and usually go out of our way to find out the best practices that we can use to improve our yield. Other than that, we also take the time to share the knowledge we gather through discussions and exchanges with other gardening enthusiasts and experts. Information is free for all, and by sharing, we all learn how to make our world a better place.

The ​​Soil ​Test ​Kit reviews we have in here are accurate, having been tested by experts, and under controlled environments. The soil samples were specifically chosen, given that we already knew the content of different soil components, and used the pH meters to determine their accuracy, efficiency and the speed with which you would get accurate results.

Why Should Get The pH Meter

The one important thing that any gardener needs to do is get a proper soil test to understand the type of soil they have in their garden. Without this, you might not be able to achieve the yields you have been hoping for. You will end up spending so much on nutrients, fertilizer and so many other stuff, only for your plants to fail.

In case you are planning on gardening soon, the following are the three important reasons why the pH meter will come in handy for you:

Determine The pH Levels

Understanding the pH levels in your soil is the easiest way for you to determine the nutrients that are available in the soil, which the plants will absorb. Your soil sample might actually have the right quantity of nutrients for your plants to thrive, but since the pH is either too low or too high, the plants will not benefit from these nutrients.

A lot of plants generally thrive in soils with a pH level of between 6.0 and 6.5. There are also some unique plants, like blueberries, that thrive in acidic environments, with a pH of between 4.5 and 5.5. Salvia, on the other hand, thrives in an environment with a pH of between 7.0 and 7.5.

Simply put, plants are different in their needs, but most plants survive in the pH region between 6.0 and 6.5 because the nutrients that they require are easier to access at this level.


Most of the urban plots and gardens usually have a high chance of having some toxic matter. This is particularly so in the event that you are planning on planting your crops on a piece of land that was once a vacant lot. The most common result usually indicates the presence of heavy metals in the soil sample. With the best soil pH meter, it is possible for you to determine what metals or toxic matter is present in the soil.

Should there be heavy metals in your soil sample, but in trace amounts, you would have no cause for worry. This is because the plants would benefit from the presence of things like zinc, copper, manganese or iron, but in the right quantity. However, at the same time, the soil sample will not be ideal for your plants in case you find things like cadmium, lead or arsenic.

Besides, the presence of toxic metals and materials in your soil sample would affect your decision, especially if you were to consider the production of edible crops. Perhaps you might be advised to consider remediation before your garden is ready for edible crop production. You might want to replace the soil with clean soil or let the ground lie fallow for a while so that the present toxins can be used up by the non-edible plants before you go ahead with your plans.

Micronutrients and Macronutrients

One of the other reasons why the best soil pH meter will help you a great deal is by determining a number of nutrients present in your soil sample. This is basic knowledge, especially if you understand the important role that different nutrients play in the growth process of plants and their absorption.

Plants generally need potassium, phosphorous and nitrogen in larger quantities than they need nutrients like magnesium, sulfur, and calcium. These are the primary and secondary nutrients respectively. There are micronutrients that are also needed, but in smaller quantities, like nickel, molybdenum, copper, zinc, iron, manganese, chlorine and boron. Though the plants will not suffer without them, they are still important to the optimal growth of the plants, and to support different plant functions.

It is important to note that most of the DIY test kits barely test for micronutrient levels. For this reason, you might have to go for a proper lab test to determine their presence. However, most of the soil samples generally have the trace elements in the right quantities, and deficiencies are not as common as that of macronutrients.

How We Chose And Tested

To determine which of the pH meters was worthy of this review, we selected 10 of the top selling pH meters in the market and got independent tests from lab technicians. The tests were done using different predetermined test samples, to enable us to see the ability of the pH meters in detecting the different components that were in the soil samples, including trace elements.

It is from this that we were able to notice the difference in operation and accuracy of the pH meters. Some were slow, slower than what they are advertised to be on the internet. Some were not able to get the results that they are supposed to, with the accuracy they are marketed to deliver. We then narrowed down to the pH meters that showed the accurate results and came up with this review.

Other Great Options:

This test kit features a test range of 1 – 10. Within this range, you are able to know whether you are in a wet area (blue zone 8 - 10), a moist area (4 – 8 green zone) or a dry area (1 – 3 red zone). It has an indicator that reads the moisture level, the readings of which will help you promote the healthy growth of your plants.

What we like about it, is that you do not need batteries to use it, neither do you need electricity to run it. You simply plug it into the soil sample and you will get the readings on a scale. In case you need to check water levels, this is a good option.

Perhaps the challenge we have with it is that it does not really tell you what you are looking at. You might not even know what the measurements are about. Another issue we have with it is that it is very easy for the tip to break.

One of the reasons why we selected this soil pH meter is because you get accurate results, very fast. It has also been recommended for use in class lessons, by professionals or for the average gardener. It is, therefore, an effective kit for all your soil sample needs, and you can even teach your kids how to use it.

We, however, noticed a few challenges with this kit. For all its effectiveness in operation, it is a pity that the plastic filtration device seemed to split right at the seam. Other than that, we also struggled a bit to learn how to use the plunger system. The kit has a chemical test, which we realized most gardeners would not really need.

In order to make sure you have a higher chance of getting impressive results all the time, this pH meter has a dual probe system. By giving you accurate readings for the pH in your soil, it is easier for you to know what you are working with all the time.

To make work easier for you, this test kit also comes with instructions on how you can test different soil samples, and you will also know the best way to balance the pH levels in your soil or the best way to keep it in control.

One of the reasons why this kit features in our review is because of the great price. You are getting some good quality performance at an impressive price. Compared with other budget pH meters, it is one of the easiest to use and will provide simpler and clear results.

What we find unpleasant about it, is the fact that it seemed to break easily, and depending on the temperature, at times it is not as sensitive as you would expect.
