This means that areas of relative high conductivity, such as the ring of sapwood and bark, shown in blues in an ERT, are more conductive than the “dryer” heartwood in spring, summer, - 5 - Promat (HK) Limited | Tel: (852) 2661 2392 | Whatsapp: (852) 5196 8861 | Email: sales@Promat.hk | Web:... -
Page 6: Electrodes
In general you can use any type of conductive metal electrodes to take ERT measurements. We recommend electrical galvanized nails, which can be used for taking both sonic and electric impedance measurements. - 6 - Promat (HK) Limited | Tel: (852) 2661 2392 | Whatsapp: (852) 5196 8861 | Email: sales@Promat.hk | Web: https://www.promat.hk... -

Sapwood cannot be found if distance between the MP is too large. In many cases it is best to use twice as many MP as you would use for SoT measurements. - 7 - Promat (HK) Limited | Tel: (852) 2661 2392 | Whatsapp: (852) 5196 8861 | Email: sales@Promat.hk | Web:... - Page 8 In order to detect/measure the size of outer layers such as bark/sapwood, the distance between MP should coincide with the thickness of the layer expected. - 8 - Promat (HK) Limited | Tel: (852) 2661 2392 | Whatsapp: (852) 5196 8861 | Email: sales@Promat.hk | Web:...
