Precision material humidity measuring instrument HM810

Professional material humidity measuring instrument with integrated measuring needles, 493 integrated material characteristics, Hold and Auto-Hold function, automatic and manual Temperature compensation, 9-level humidity evaluation (wet ... dry), Sort function, automatic switch off

Note: Measuring principle is based on measurement of conductance between two electrodes (resistive measuring method); due to its wide measuring range, it is suitable for all sorts of wood, minerals (e.g. gypsum board, porous concrete, or flooring) and other materials
