Environmental Concepts Dual Probe Soil pH Meter uses an exclusive two-probe measuring system which allows both probes to be inserted to the same depth in the soil and allows the metals to be exposed to the same amount of soil providing the most effective way to consistently and properly measure soil pH. Full instructions for use and adjusting pH after readings are included along with cleaning pad. The logarithmic scale plate is easy to read and measures as wide range of pH.

I was interested to find out why my zoysia grass was growing well in my backyard and not so well in my front yard.
I stuck the probes in the ground after cleaning per instructions, the soil was moist and lo and behold a PH of 4.4-5 in the areas where the grass was growing poorly and a PH of 6,-6.5, -7 in the healthy areas.
The deeper I probed the higher the acidity (as low as 4) as I started to slowly remove the probe,the PH would begin to increase to 5.5. then 6, so I could begin to see the topsoil was deeper in the backyard and shallow in most of the front yard.
I will treat with lime this fall. I had suspected this was the problem. My house is only three years old so the sod was just laid three years ago.
1. Clear instructions stating to put some dirt into a container, add distilled water and read the PH that way instead of trying to stick the very thin probes into the hard ground. They will break.
2. Clean the probes every time you use them.
3. Wait a full minute before taking a reading, the meter will peg into a direction, then back to center, then it will begin to move in the direction of the PH reading.
I will say to everyone here that is growing outdoors to till and amend your starting soil with dolomite lime which will automatically make the soil PH come back to neutral. The cup testing method works to some degree but most of the time its best to till, soften ,and test directly in the ground. The use of distilled water is questionable considering it usually has a lower than neutral PH, using a neutral 7.0 batch of water will have less influence on soil PH after being saturated.
You need to take the PH from the soil your roots are sitting in, take a top soil reading and if possible a root level reading as well.
Taking soil out of a grow container to do a test will not give you a correct root soil PH and disturb your root progression, best to soften the soil in the pot first w/ neutral filtered water and test directly in container .
Great product for the price :) 4 Stars
