Notes for wood moisture measurement The measurement of wood moisture is carried out with the Hydromette BL A plus using resistance measurement or capacitive measurement. The wood moisture is displayed in percent by weight in relation to absolutely dry wood (ATRO).
M 18 ram-in electrode for thicker or particularly hard woods. If possible, the hexagon nuts should be tightened with a spanner or pliers before beginning a series of measurements. Loose electrode tips break off easily. Hydromette BL A plus...
For measurement in chips and wood wool, it is advisable to compact the material to be measured slightly. To do so, sawdust should be pressed together with a weight of approx. 5 kg. No compression is necessary for balls of wood wool. Hydromette BL A plus...

Application Notes 5.1.2 Notes for capacitive measurement Measurements with the Hydromette BL A plus must not be performed on a conductive surface (e.g. metal). For wood thicknesses of less than 40 mm (e.g. veneers, strips, etc.), either several layers must be laid on top of each other until a minimum thickness of 40 mm is reached, or the selection for thin material thicknesses must be selected in the menu.
