If you have grown your own garden or you constantly deal with live plants, a pH meter is almost mandatory for you. What a pH meter allows you to do is monitor the current hydrogen-ion activity in water-based solutions. The device will display for you the current acidity or alkalinity level of the solution you are measuring.

This “number” is known as pH. Knowing this number can be crucial as changes in pH can affect the plant’s nutrition and its growth. But, some soil pH meters are designed to measure more than just soil’s pH levels. On top of this, there are some digital and non-digital versions to choose from.

Criteria Used for Evaluation

Use

One can never assume, but, most likely, you came here today only interested in finding a meter to measure the pH level of your soil. As you read through this guide, you got a clear understanding that these devices offer more functionality than just pH readings. But, this is their main functionality; there is no doubt about that. Yet, what on earth is a pH level and why do you need to know it?

As mentioned earlier, pH is a measurement to find out the relative alkalinity or acidity of a substance. In this case, this would be the soil beneath your plants. It generally runs from 0 to 14 and the lower the number, the more acidic it is.

This becomes important because, for some plants that require acidic soil (pH levels around 4.5 to 5.5), you want them to have the correct pH level. The same goes for plants that need a higher pH level and a soil pH meter allows you to determine that. However, sometimes they offer further functionality.

For example, they may also measure the current moisture level and if the soil is getting enough sunlight. Both of these metrics are vital to a plant’s growth, as well.

Accuracy

The entire purpose of owning a soil pH meter is to better gauge the health of your plants and if they will survive. You do this by knowing the pH level (among other measurements) and reacting accordingly. But, what good is this is the pH readings your device is outputting are inaccurate.

If it is off by maybe 0.3 or 0.4 that is not too big of a deal but when it plus or minus one or two pH, that is major. When glancing over a pH meter, you may see a manufacturer rating in the specifications. Typically, this will indicate the plus or minus accuracy guaranteed from the meter. Can you trust that number or should you take it with a grain of salt?

That question is hard to answer and the best precaution you can take is to judge user feedback. See what actual customers have claimed about their real-life experiences with the pH meter. If the general consensus is that the meter is precise with others, chances are the pH reading is going to be almost spot-on with the actual level.

Ease of Use

You will fall in love with your soil pH meter for many reasons but one of the main reasons may be due to the simplicity. A lot of times with these devices, it is as simple as inserting the probe into the soil. From there, some devices will require you to press a button while others will automatically begin measuring. About the only task that will require a bit of effort on your part is the calibration, and it is still not that much.

If you are using a soil pH meter that is specifically designed to be inserted in soil and nothing else, try letting it sit in the soil for a while to allow for a more accurate reading (if it seems to be inaccurate). But, most of the soil pH meters on this list will not need to be calibrated. However, for other pH meters, you can dip them in a solution of pH value seven and allow them to stabilize. Either way, the process should not be too difficult.

Features

Without a doubt, one of the biggest questions you need to ask yourself is whether or not you require a digital display. Part of the reason why there are a few pH meters on this list that require a bit of work to measure soil (even though still feasible), is because they have a digital interface. Sure, this brings along with it the need for batteries but some will enjoy the luxuries of an LCD display. On the other hand, most basic soil pH meters will have a meter that displays the readings.

This is not necessarily a bad design aspect but at the same time, sometimes the meter display can be painfully small. Oftentimes, you will find yourself squinting to see the measurement especially when they, typically, measure more than just the pH level. Though, do not assume that all non-digital displays are horrid. As long as you can view a clear image of what you are trying to read, it should suffice.
