There are three methods for measuring concrete: Pin-Pinless-Insitu RH. Measurements in pin or pinless mode allow instant evaluation of concrete. When installing resilient floor coverings, both pin and pinless measuring methods are not approved by the floor covering manufacturers to determine whether or not a floor can be installed. Check the floor manufacturer’s manual to find out, which test is required to guarantee the manufacturer’s warranty.
- Pinless measurements reach 3/4″ deep. Considering the thickness of a concrete slabs, the measurements only give information about moisture close to the surface.
- Pin measurements can reach up to 7″ deep with EL pins. Two holes will have to be drilled. When drilling to different depth levels a moisture profile in the concrete slab can be established to a depth of 7″.
- In-situ RH test for concrete moisture. All accessories are available for RH insitu probe testing to follow ASTM F2170. The test takes 24 hours.
The Ligno-VersaTec is the meter, which allows for all three modes when measuring moisture in concrete: Pin-Pinless-Insitu RH.
