The impact electrode M 20 can be used directly for wood moisture and building moisture measurement and also serves as a base system for various other electrode pairs (see below).
The electrode can be used with all hydromettes based on the resistance measuring method.
The electrode body is made of impact-resistant plastic.
The scope of delivery includes 10 electrode tips of 16 and 23 mm length each.
Measuring range wood moisture:
Suitable for moisture measurements in wood up to 50 mm thick.
With the aid of a suitable impact device (e.g. hammer), the electrode can also be driven into hard woods such as beech.
Measuring range for building moisture:
Suitable for moisture measurements in soft, set building materials (e.g. plaster, gypsum or aerated concrete).
For depth measurements in gas concrete etc. up to approx. 70 mm, electrode tips with a length of 60 mm (order no. 4660) can also be used.
The electrode also serves as a carrier system for various other electrode pairs, i.e. the probes listed below can only be used sensibly in conjunction with an M 20 electrode:
