Good morning everyone, Let me know if anyone is or is not going to make it to today’s Live Call! It’s to be at 2pm PST

You don’t want to be in this contractor’s shoes.

One trend that keeps accelerating: manufacturers are explicitly calling out ASTM F2659 electrical impedance meters as approved tools for moisture evaluation. This is a big shift from a few years ago, when these meters were often treated as “screening tools only.” What’s driving it? ✅ Non‑destructive testing Manufacturers want moisture data without drilling, patching, or damaging assemblies—especially in finished or occupied spaces. ✅ Speed + coverage Impedance meters allow technicians to scan large areas quickly and identify moisture patterns, not just point‑in‑time readings. ✅ Repeatability ASTM 2659 provides a standardized method, which gives manufacturers confidence in consistency across jobs, techs, and regions. ✅ Better decision‑making Instead of guessing where moisture might be, manufacturers can now require documented scans before remediation, flooring installs, or warranty decisions. What this means for contractors & inspectors: • If you’re not using an ASTM 2659‑compliant meter, you may already be behind manufacturer expectations • Documentation from impedance scans is becoming more defensible • “Approved tool lists” are expanding—and meters that meet ASTM 2659 are showing up more often Important note: Impedance meters still don’t replace in‑situ probes or RH testing where required—but manufacturers are increasingly recognizing them as a legitimate, primary assessment tool for many applications.

And how has that changed the way you test or report moisture?
