Wood Moisture

Modification Set
M 20-DS 16-i

Ref.Nr. 31004311
For moisture measurements of wood fibre insulants with insulated electrode nuts


The conversion kit M 20-DS 16-i is used for the measurement of moisture content of wood fibre insulants. It contains special insulated electrode nuts, which reduce the impact of surface moisture. If other electrode nuts are used, this may result in false readings.
