I have had this product for about 10 months now and it is by far the best pH meter I have ever used. Taking manure samples and determining the pH of the soil has never been easier. All this in one controller and it's very easy to calibrate. I keep the probe in storage solution and it works wonders. Last night I went to calibrate my meter for the first time in 6 months and it read 7.0 and 4.0 exactly. I used to have to change cheap meters every 6 months and who knows how accurate those readings were. Inspires me to write a review!
