Drive-in electrode for measuring wood moisture and structural moisture

DescriptionUsecases

Description

The M 20 is a drive-in electrode for measuring wood moisture and building moisture. It is based on the resistance principle of measurement and can be connected to all corresponding measuring devices.

The electrode is suitable for measuring the moisture of sawn timber (up to 50 mm in thickness), chipboard or OSB, and parquet for example.
By means of a suitable impact device (e.g. a hammer), the electrode can also be driven into hard woods such as beech.

It can also be used for measurements in soft set building materials (e.g. plasters, gypsum or aerated concrete) as well as insulating materials.
