Protimeter – BLD4711 Humidity Box – Concrete Moisture Measurement Accessory

Protimeter - BLD4711 Humidity Box - Concrete Moisture Measurement Accessory

The Protimeter BLD4711 Humidity Box is designed for measuring relative humidity in concrete slabs. It works by trapping a pocket of air against the surface of the concrete, allowing the air inside to equalise to the slab’s humidity. The moisture level can then be measured accurately using a Protimeter MMS or HygroMaster meter with a Hygrostick sensor and extension lead (sold separately).

Compact and durable, the BLD4711 is an essential accessory for flooring contractors, building inspectors, and restoration professionals performing concrete moisture diagnostics.
