Description

The M 18 is a ram-in electrode for measuring wood 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 in thick wood and in hardwood (up to 180 mm).

The user should put his palm on the top of the electrode to keep it in its position. Then it be rammed into the wood by moving the handle up and down.

Measuring ranges

Measuring Ranges
min.4 to max.100 % (dry mass)
min.31 to max.41 % water content

The actual measuring range depends on the connected measuring instrument.
