As with all these types of portable meters, readings in building materials (brick, plaster and concrete) are qualitative and not quantitative, therefore they are used as a relative reading for comparative purposes only (i.e. compared to a know dry area). Different meters, different methods of testing, density settings, penetration depth, surface conditions, porosity of materials, aggregate size etc. all affect the results and it is unlikely any two meters of different types, method and settings will read the same.

Hydro-Tec is a portable moisture meter designed for fast and convenient moisture measurements of wood and building materials (concrete, masonry, brick). The Hydro-Tec measures the moisture content of a material using capacity technology, not damaging the material’s surface. It ensures accurate moisture measurement at a depth of up to 20mm within a working range of 0.1-65% (material and density dependant). Despite its small size, the moisture meter is equipped with a “Material database” that consists of 9 groups of materials, including 23 types of wood such as spruce, willow, cedar, poplar, aspen, alder, pinewood, basswood, birch, walnut, hazel, larch, cherry tree, elm tree, beech, teak, oak, pear tree, ash wood, yew, hornbeam, rosewood, and meranti. Moisture meter Hydro-Tec is a great solution for those who need a high-quality professional instrument for wood and building material moisture measurements. This makes the instrument to be in popular demand among builders, woodworkers, furniture makers, carpenters and quality inspectors.
