By Andrew Wowk on May 21, 2009
I purchased this product from a local hardware store. I have also purchased another ph meter that works on the same principle made by Mosser Lee. Both units appear to be of no help in determining ph to any degree of accuracy, nor in adjusting ph. They *may* be of slight help in determining if soil is either way acidic or alkaline but nothing beyond that.

I first used it to test a control sample of soil from my area that should measure about 7.8 ph (this is a desert and the soil is alkaline). Additionally, the water here is likely alkaline but I have not measured it yet. I followed the instructions to test a sample with tap water (unfortunately I did not have distilled water available), and the meter instantly flung all the way positive, then slowly settled back to neutral (7) where it started at.

Next, I took 1 cup of water and added about a teaspoon of baking soda. I know this is not how the meter was designed to work, e.g., measuring water, so if it still measured neutral than I would still not count it as bad. Sure enough, it measured neutral.

My hope at this point was that the unit was mis-calibrated. So I took the sticker off from the front that is directly underneath the display and adjusted the lever so that the meter would read about 7.8 when testing my control soil sample. Next I measured a cup of vinegar (5% concentration) which measured about 2.5, so I figured that I was on to something. Maybe the meter just needed to be properly calibrated?

I proceeded to adjust the ph of soil for a potted plant. In concentrations of about 4 tablespoons per cup, I added about 12 ounces of vinegar in total, each time observing the ph drop a little. NOTE: I inserted the ph meter at an angle to read the top layer of soil that was soaked with the acidic solution.

I became frustrated with my PH/Fertility soil tester. I came to these reviews to learn what I could. I discovered I was being as silly as many of the others in trying to use this measuring instrument. I couldn't expect a 2 bit gauge to earn 5 stars. I am a craftsman & furniture maker, so am naturally methodical, detail conscious & mechanically inclined guy. After sitting down to read practically every word of the instructions, I became aware there were little things that could result in mistakes in using the instrument. One has to keep in mind, this is a cheep little gauge. If it was all the technology required to measure soil PH & fertility, there would be no expensive ones made. Any cheep tool, particularly a measuring instrument, you need to coax the truth out of it. This means meticulously reading the instructions with a high-lighter; sometimes reading between the lines.

As an example, between initial attempted measurements, I would draw the probes thru my fingers to clean them, then wipe them off on my jeans, then use the wetted cleaning pad that came with the gauge. Upon scouring the instructions, among many ways that I tightened up my technique, I quit touching the probes with my fingers. As I was getting progressively more stupid results from the gauge, I think my hand oils were building up on the probes. I washed the probes in dish water. From then on, between measurements, I would 1st wipe the probes off with a soft, clean cotton cloth, then wipe them off with the wetted pad that came with it.

There were several "bench tests" that I did, where I had a rough idea of the way the gauge should respond ...the thing started giving me readings that made sense! My bench tests were not as far away from reality as sticking the probes in a can of orange juice!! give me a break!!

Worthless out of the box. Purchased today (02APR2016) @ Lowes.
Needle defaults at 7.0 pH (water) in off position.
Inserted brand-new alkaline battery.

Testing:
1) Moved to bleach to measure 11.0 - 12.0 pH bleach solution (switch @ pH switch position):
No needle movement (7.0 pH).

2) Moved to water to measure 7.0 pH (switch @ pH switch position):
No needle movement (7.0 pH).

3) Moved to vinegar to measure 2.4 pH solution (switch @ pH switch position):
No needle movement (7.0 pH).

4) Kept probe in 2.4 pH vinegar solution (switch @ fertility position):
Needle measured 2.4 pH

Hypothesis: switch wired wrong

5) Moved probe to measure 11.0 - 12.0 pH bleach (switch @ fertility position)
Needle pegged high > 9.0 pH, then slowly pegged low < 1.0 pH, then crept back up to 3.0 pH and remained.

6) After switching probe back and forth between bleach and vinegar several times, a reliable pH RANGE was never achieved with the switch @ fertility position. The needle proved to simply sweep positively for bleach and negatively for vinegar.

7) Moved switch to pH and switched probe between vinegar and bleach several times. A reliable pH deviation from 7.0 was never achieved with the switch @ pH position. The needle proved to simply sweep back and forth wildly when changing solutions.

8) Moved switch to OFF and switched probe between vinegar and bleach several times for several minutes (longer than any capacitor should take to discharge). The needle proved to simply sweep back and forth wildly when changing solutions.

9) With the switch in the OFF position, accuracy does not seem to be impacted.

10) Next test... removing the battery. I think you all see where I'm going with this. I doubt I'll post the results.

Taking this garbage back to Lowes ASAP.
