This gauge is a standard wire strain gauge with a transparent plastic backing impregnated with a polyester resin. It offers several remarkable features, such as excellent electrical insulation, easy and accurate installation, and quick setting. Gauge lengths are available in 3 steps from 60 to 120mm, making it well suited to the measurement of concrete strain.
