How many relative humidity tests should I use on each job?

For the Flooring Contractor and as part of the project documentation process, ASTM F2170 requires that 3 tests be placed in the first 1,000 square ft. and that one test is placed every 1,000 square ft. thereafter. If you are using the Rapid RH® system as a monitoring tool early in a project to determine when final acceptance testing should be performed, several Rapid RH® 4.0 EX Smart Sensors can be placed throughout the floor 28 days after the pour and readings taken as often as desired.
