How can the HygroBug™ help monitor drying of damp concrete?

Drying from surface can mislead as to in depth humidity if measurements are done at the surface, or …
… Equalisation period is too long, and …
… salts and impurities can distort results.
Conductive materials can with traditional measurement techniques indicate materials are saturated when they are actually dry, while …
… capacitance type “in-hole” sensors are sometimes too slow to respond to subtle shifts…
… especially at very high levels of Humidity…
… and the tolerance range at high RH of some capacitance sensors gets very wide, eg +/- 5RH at saturated levels
Variation within slabs, and from slab to slab means quick, cost effective, reliable monitoring from multiple locations is desirable
Continuous real-time monitoring is needed to understand what is going on during drying, and afterwards in stabilisation.

low cost & consistent [so can be deployed in multiple locations]
Provides a reliable measurement which is not distorted by conductive materials
very responsive AND stable at very high RH % as well as “normal” RH %
can be fitted at various depths in the slab
connects to any HygroNet system for real time & on-line monitoring or any proprietary Hygrometer with a resistance WME input 3.5mm jack point
Consistent, so allows benchmark drying
Low Hysteresis and fast response so suits on/off/on/off heat drying regimes
