Protimeter Humidity Box (for use with Protimeter MMS and Hygromaster)

Protimeter humidity box for surface RH measurement

A box that seals to a solid floor and lets the air beneath it equilibrate, so surface relative humidity can be measured without drilling.

Surface box or in-situ sleeve?

They answer different questions. The humidity box measures the humidity at the surface of the slab, without drilling. A humidity sleeve set into a drilled hole measures humidity at depth inside the slab.

Deep moisture is what fails a floor after an impermeable covering goes down, so a surface reading alone is not a substitute where the specification calls for in-situ testing. Check which method your flooring specification actually requires before you commit — installing to the wrong test is a mistake that only surfaces once the floor lifts.

The box is the right tool where drilling is not permitted — post-tensioned slabs, finished floors, tenanted buildings — and for a fast comparative survey before committing to a full in-situ test.
