Thanks for the feedback. We are using a Wagner model with separate probes. Given that the slab is 3". Are we correct in that the depth of the hole for the probe should be appx 1-1/6" deep? We were reading and came across a post that said the hole is to be 40% the slab depth. The holes that were used for the previous test are over 2" deep.
