Description
Use to assess the moisture content of concrete floors.
The Digital Humidity Box is left in position for long enough for the entrapped air to reach moisture equilibrium with the floor. Rough or uneven floor surfaces neccessitate the use of hygrometer strip sealant. A floated floor finish will need longer than a rough open finish. 2 or 3 days may be required.
A value for the entrapped air of 75% RH or less is typically considered to indicate that a sand and cement screed or concrete floor is sufficiently dry to cover with a floor finish.
