Has anyone (like concrete construction) published a series of RH tests using 4.0 & 5.0 tests over time in the same slab?
I'm wondering if the 5.0 probes get lower readings than the 4.0. I know that one of the testing companies in my area that uses (non wagner) reusable probes always seems to get results slightly lower than mine.
