Good Soil Ph Meter Anyone?

It sounds like i got ripped of by Home Depots 3in1 ph meter for soil what would work good and accurate????

Any digital ph meter. I just ebay around for em, the basic stick models ($40-50) are all the same thing in a different parcel.

I'd skip on the probe testers, you'll probably end up throwing it away or letting your plants die. My plants were having a chronic deficiency which was not solved by more fertiliser and seemed to be temporarily helped by flushing. I always had a confusingly neutral PH with both of my testers and my suspicion kept growing until one day I decided to try dipping one of my probes in vinegar. Neutral vinegar... yeah. Then I rubbed it with steel wool and got the same result again. Turns out a concentrated sodium bicarbonate solution is about the same PH as 5% or 2.5% acetic acid. One tester would move up .5 weather it be testing an acid or base and the other would do nothing.

I tested the soil with one of the chemical test kits and the PH was quite low and there was too much N because I had been feeding more and more chemical fertiliser based off wrong information. In my experience a probe tester is about as good as just assuming your soil is ok. I think they're just selling them because people like me buy them twice thinking another brand will be better than the first.

The chemical testers require a large sample and is more work but it will at least give you results, albeit not pinpoint accurate, and it will give you an idea of the NPK content of your soil. If you really wanted a truly accurate and reliable test you have to use knowledge of chemistry or ship a sample off to a lab.
