VI-D4 meter calculates humidity of analyzed material by measuring its electrical impedance. The relation
• between humidity of certain material and its impedance is directly proportional. Impedance is measured through
• generating low frequency electric field between electrodes. The meter measures low intensity alternating current
• flowing through electric field and on that basis calculates moisture of tested material.
