Selector Best New Product Award 2011 finalist: Electric Field Vector Mapping (EFVM) system.

Electric Field Vector Mapping system

The Electric Field Vector Mapping (EFVM) system is a low-voltage test method that creates an electrical potential difference between a non-conductive membrane surface and a conductive substrate, which is earthed or grounded. The ILD EFVM systems allow pinpointing of membrane breaches through a non-destructive process using a very limited amount of water, especially when compared to traditional “flood” style leak detection processes.
