Bests & Worsts Reviews from Amazon

I bought this moisture meter to check for moisture in my crawl space. I conducted an experiment with some pieces of wood to see what it measured for various conditions. I figure it's good to do this yourself, so you know how to interpret the results against a known sample. Dry piece of 2x4, from my garage - 11.9% Chunk of cedar from outside wood pile, not recently rained on - 12.9 to 14.1% Chunk of cedar recently rained on - 24 to 26% Chunk of cedar, soaked in a bucket for 30 minutes - 27 to 30% The meter is pretty easy to use. One button turns it on, one button switches between building material and wood mode, and another button holds the reading. It emits a constant beeping noise and will beep faster the wetter it is. It comes with a battery. Prongs are good and sharp. Seems like a decent meter.
