Reliability of RH Testing Using Removable Proves vs. Insitu Probes?

RE: Reliability of RH Testing Using Removable Proves vs. Insitu Probes?
The 75% requirement is set by adhesive manufacturers and varies with each product used.

The Rapid RH does a very good job of isolating the test sensor at the 40% depth (or 20% when drying from one side). It is true the sleeve readers take a long time to acclimate, and must have had the calibration checked within the last month. They must also be watched for drift.

I have used many different Rh testing devices and have found the Wagner to be far and away the most reliable, repeatable and accurate device for testing RH.

My livelihood depends on accurate RH readings, and oftentimes I find myself in direct conflict with several other RH reading devices on a job site. Many times I have had to prove my RH readings, and the Wagner Rapid RH has never failed me. It's the only one I will use or recommend. [/quote]
