The Absolute Moisture Meter RH-2 can measure various parameters: relative and absolute air humidity, temperature, dewpoint as well as water activity in wooden materials. The equilibrium moisture content of the thermal dewpoint calculator indicates the relative ambient humidity, which the material has an equilibration with, and thus is unable to absorb or to emit any more humidity. The absolute humidity of this group of test instruments detects the percentage of water content based on gross weight of the material.
