Elektro Physik MiniTest 7400 FH Wall Thickness Gauge
The Elektro Physik MiniTest 7400 FH Wall Thickness Gauge is a magnetic thickness gauge with a 24mm measuring range, 0.1µm resolution and ±1µm repeatability. Elektro Physik MiniTest 7400 FH thickness gauges are suited for the thickness measurement of non-magnetic materials such as glass, synthetic materials, stainless steel and composites, and also the measurement of complex component geometries. The Elektro Physik MiniTest 7400 FH's SIDSP sensor ensures high measuring precision and repeatability and compensates for temperature influences of the measuring environment and the measurement object. The sensors are equipped with carbide metal tips making them highly wear-resistant.
