FLM/WFLM series Metal backing strain gauge
This gauge has a thin stainless steel backing which prevents the lowering of insulation resistance caused by the penetration of moisture from the concrete surface. It is suited to long term measurement. The WFLM has integral lead wire and moisture proof coating over the gauge.
