pH Meter Recommendations
« on: August 06, 2012, 11:58 AM »
I am looking for recommendations on soil pH meters for general use. I don't want the $400 lab quality, just something reasonably priced and reasonably accurate. Thanks

I don't have any experiences with pH meters that you are supposed to be able to pin directly in the soil.
 I have bought a cheap pH meter in a hydroponic grow shop and was satisfied with it. Was didn't satisfied me was the time required to obtain water aliquots with the pour through method. After 2 seasons where each  measure was satisfying (I have very soft well water), I have stopped using it. (I can say the same for my conductimeter).

While looking back, I am inclined to think that pH paper put under a draining hole when watering would be  precise enough, cheaper and more user friendly. It does not give though, the satisfaction to know the pH with 0.1 precision.

My two cents.

This is what I was taught to use while in Greenhouse Management.  It's not fragile, it's reliable, and using the "pour-through" method, very accurate.  Splash some R/O water in and test a new sample. 

I've used a bunch of cheap and super expensive ones, but find the expensive ones a bit to touchy for work outside a

Just make sure you get an Agrimeter with Electroconductivity and pH testing functions.
