https://www.lanequalitys.com/products/eu100-eletromagnetic-ultrasonic-thickness-gauge.html EU100 Eletromagnetic Ultrasonic Thickness Gauge Pen type electromagnetic ultrasonic thickness gauge manual is an ultra-small non-contact measurement instrument without coupling agent, which can measure the thickness of metal materials at room temperature and high temperature. It is suitable for titanium, aluminum, steel, stainless steel, alloy steel, carbon steel, cast steel, etc. Features of EU100 Eletro Magnetic Wall Thickness Gauge Ergonomically optimized design. Compact structure, ultra-small size, easy to carry, fit the sense of grip. Accurate thickness measurement, measurement through coating, no coupling agent and grinding of workpiece surface are required. Paint, coating and unevenness are allowed on the tested surface. Various material sound velocities are pre-stored in the instrument, and material sound velocities can be added and deleted dynamically at the same time. The sound velocity calibration increases the temperature compensation function and improves the measurement accuracy.
