Moisture meters


  • Objects which can be measured with the electric moisture meters are an electric insulator or asemiconductor. These are shown equivalently as a parallel circuit of resistance R and electrostatic capacity C. Moisture contents are measured utilizing these electrical characteristics.
  • The electric moisture meters are classified into two types, one utilizes the change of resistance R and the other utilizes the change of electrostatic capacity C.
  • As the relation between moisture and resistance or capacity is different by a kind of materials, several kinds of meters are provided for each object to be measured such as for wood, paper, mortar, etc. or the meter which is applicable to the object to be measured by changing a type of the probe.

Remarks on measurements

  • Electric Resistor Type Moisture meters use the applications of sensitively electric characteristics of measuring objects against the moisture contents and the corresponding relations never be a perfectly correlative one-to- one.
  • In case of measuring with different compositions &combinations, albeit the same material , or with changes in quality, contamination, and furthermore with special processing, chemical treatments, it may be necessary to avert measuring such unfavorable objects, and compensate or average measured values. As for compensating, it is, in general, based on moisture measurement methods in accordance with a drying process.
