Best Soil PH Meters In 2021

The Luster Leaf 1601 Rapitest Test Kit brings outstanding value for money. This chemical dye pH meter is simple enough to use by the novice, yet accurate enough to satisfy the professional gardener or landscaper. It contains components to test the acidity of your soil for 10 times and comes with a handy list with the soil pH preference for over 450 plants.

Besides the soil pH test, the kit also comprises tests for nitrogen, phosphorus, and potash. These are important nutrients for the plants, and you can use this soil testing kit to check their level in spring, fall, and periodically throughout the growing season.

If the chemistry is not your thing and you’d rather read the results on an analog screen, check out the Sonkir MS02 3-in-1 Soil Tester. This handy device tests soil moisture, pH value, and sunlight level of the plant, letting you know if you’ve seeded it in the right spot. Accurate and reliable, it’s also ridiculously easy to use. It needs no batteries, and all you have to do is stick the sensor probe about 4 inches deep into the soil.

Its double-needle detection technology enhances both testing speed and result accuracy; just toggle the switch in the right position and wait until the pointer stops swinging, then read the value on the dial. Ideal for both outdoor and indoor use, lightweight and portable, this is another excellent soil pH meter to test the soil of your garden or plants on your potting bench.

An interesting pH tester, ideal gift for gardeners who don’t mind to drop some bucks, the Kelway Soil pHD Soil Acidity Test is up to an extent similar to the Sonkir. It won’t measure moisture and sunlight, but it still uses a probe you’ll have to stick into the ground.  The device utilizes a tiny flow of electricity running through two metal plates to measure the pH, indicating the value on a dial.

Just like other probe meters, it doesn’t require a power source; however, there are mixed feelings about its accuracy. Some users claim the tester might return random values. When checked against other testers, however, we experienced none of this. We also like its handheld size and that it’s easy to operate. Easy to use and reliable, this is a great device if you don’t mind its heftier price.

If you couldn’t care less about moisture and light measurements but like the two probe concept, the Environmental Concepts pH7 might be the right soil pH meter for you. This simple device is similar to the other probe testers on this list, but it’s built to only test the pH level of your soil. This simpler construction comes with benefits. On the one hand, the unit’s permanently calibrated, which means more accurate results. They are displayed on an easy to read logarithmic scale, and what’s even best, it measures almost the entire pH scale.

Coming with full instructions and indications on adjusting the pH, this meter will surely help you grow healthy plants. However, it will only return accurate readings if you use it right. Don’t just stick it into the ground. You’ll have to get a soil sample and mix it with distilled water, then read the pH. Simple maintenance involves cleaning the probes before and after each reading; if used right, you can expect it to help you help your plants to thrive.

1662 Professional Soil Test Kit is really easy to use and comes with detailed instructions alongside extensive soil and plant care guidelines.

If 40 tests are insufficient, you can also choose one of the other options, that come with 80 or 200 tests respectively.
