Plants need the correct pH (acidity/alkalinity) level which control how well plants utilize the nutrients available in your soil. This meter will help determine your soil pH level.

  • All plants have a pH preference, so it is important to know the pH level of your soil, You can then choose plants with the same pH preference and avoid those that will not do well in your soil
  • By testing your soil, you determine its condition so that you can adjust pH more accurately, effectively and economically
  • Easy to use, simply push the probe in to wet soil and the meter will register pH levels on a scale of 3.5 - 9.0
  • Complete details are included on how you can alter the soils pH if needed

Rated 3.0 out of 5.0 by Can tell acidic from alkaline, but not accurate My wife said it did not work since it always showed 7.0. It turns out she did not wait long enough. Wait 60" per instruction then read fine--no more 7.0 readings. Then I broght it to my lab and tested on the two standard pH solutions: for the 7.0 standard, it reads exactly 7.0; for the 4.0 standard, it took more than a minute before the reading settled at 5.1. It can tell acidic from alkaline, though not very accurate. Enough for home garden if you plants have a reasonable pH tolerance ranges. April 22, 2014
Rated 1.0 out of 5.0 by Does not work Always indicates pH of 7. Even if you dip it in vinegar. October 4, 2014
Rated 1.0 out of 5.0 by Great concept, however it doesn't work!! Stays at 7.0, regardless where in the garden/yard that the tested was done. I returned my first ph meter at the recommendation of the manufacturer, only to get a second one that also failed to move off 7.0. I suggest the store remove this brand of ph meter from their shelves. February 25, 2013
Rated 1.0 out of 5.0 by everything reads 7.0 What a peice of junk. It reads everything at 7.0. Yes it changes for a second either up or down then bang right back to 7. 4 types of soil mix 7. Acid fert added to soil 7. Coffee grounds 7. Cola 7. most colas are 3 to 4..... March 16, 2012
Rated 1.0 out of 5.0 by Reads everything at 7.0 As others have noted, this inexpensive meter reads everything at 7.0. Such unreliability calls to question other Ferry Morris products although I must admit their seeds have performed well. April 17, 2013
