Metal-backing Gage

This gage is designed for successful strain measurement on the concrete surface. It has a thin stainless-steel backing which prevents the penetration of moisture from the reverse side. It provides good electrical insulation to the concrete surface. The WFLM gage has a moistureproof overcoating and integral lead in addition to stainless-steel backing. Stable measurement can be achieved by bonding the gage with PS adhesive.
