The Best pH Meter – An Ultimate Guide For Your Soil

Last Updated on October 26, 2022 by Sam

It is critical to use the best pH meter to test your soils’ status to ensure your plants are getting the nutrients they need to be healthy. 

One of the most critical factors that determine if your plants will thrive in the soils’ acidity or alkalinity. If the pH value of the soil is off even a little bit, it can have disastrous effects on your plants. For this reason, it is vital to use the best soil pH testers to ensure your plants grow happy and healthy. The pH determines the availability of the nutrients that the plants need. If the pH is too low the soil is acidic with nutrients like Phosphorous being less available. Other things can accumulate in acidic soil and make it toxic. Soil that is too acidic is not a good home for beneficial bacteria. 

Soil with a very high pH is alkaline. It prevents the plants from having enough iron, copper, manganese, zinc, and phosphorous. Iron is vital to plants especially the evergreens. 

What to Consider when Buying the Best pH Meter

A good soil pH tester will get the job done each time you want to test your soil. All the soil pH readers do not have the same build. Here are key features that you need to check as you shop for the best pH meter. 

What to Consider when Buying the Best pH Meter
  1. Accuracy of the pH Meter. Always go for a pH tester that offers accurate results. Generally, there is a range that your pH must measure. It can be anything from 3.5 to 8, some ranging slightly larger or smaller. The instructions part contains details that you need to know before buying the pH tester. Pay close attention to these instructions they give you an idea of how to get the best pH meter.
  2. Probe the Depth Length of the Soil Tester. Soil pH testers come in singles or doubles designs. These probes are made out of silver, aluminum, copper, or an amalgamation of metals. The probe depth is critical – the longer the probe the better it is in giving you the best results. This is because it not only tests the top layer soil. 
  3. Single or MMlti-function. Some pH tests the soil’s alkalinity or acidity only. Others can test other factors too like the moisture content and light levels. By buying 3 in 1 test kits you will be able to test your soil of all the tests that influence your plant growth.
  4. Portability. Go for a soil pH tester that is lightweight, compact, and durable. The probes could be gentle, but the unit must be strong enough to give you value for your money. 
  5.  The power source. Most pH testers are battery-free meaning you use them without the need to plug in the batteries. Others require batteries to work. You can opt to use either of the pH testers. There is no proof that those with batteries work better than those without.

How to Read a Soil pH Meter Results 

Before you can interpret the results of your pH tester, first understand the basics of the acidity or alkalinity. These basics run from 0-14, with 7 being the neutral number. Anything above 7 is alkaline while anything below 7 is acidic. Most testers come with a chart to help you read the results. 

Most electronic pH testers have a probe that inserts directly into the soil to get the readings. In some of these cases, you might not get accurate results. The best way to ensure you get the right results is by making a mixture of distilled water and soil. Put soil in a container, add distilled water and stir so that it mixes well. With the mixture ready, you can use the pH strips or electronic tester to get accurate results. You can try it a few times to see if you get the same results especially if you are new to testing.  

Be sure to use the chart that comes with the tester. This helps you get the correct decoding for the results every time you carry out the tests.

What should I consider when shopping for a Ph meter?

The most accurate way to measure pH is with a pH meter. The only problem with pH meters is that they are not cheap and they require some maintenance, but if you are doing research or have a large area to sample, then a pH meter is the way to go. The pH scale can vary by about 0.2 units from lab to lab and even more than that depending on the pH of the water used.

If you are using a meter that isn't calibrated, it will have an error. You can buy meters that are calibrated for your soil type and the amount of acidity in your area, but even these meters will not be perfect. A good calibration can help you determine the amount of acidity in your soil and also help you understand how to adjust the readings when you dig new holes.

What is the most accurate soil pH meter?

There are a variety of soil pH meters available on the market. Soil pH is one of the most common chemical analyses performed by a home or professional gardener. The most accurate soil pH meter will give you a more accurate reading, which in turn will provide you with an idea of what type of fertilizer to use.

Many of the soil pH meters available on the market are designed to be used by a professional who has access to a lab and is trained in the use of such equipment.
