This gauge is a simple to use, high accuracy, hand-held Ultrasonic Thickness Gauge with the ability to measure through paint and coatings and even to eliminate the thickness of the paint or coating. Through-Coating Thickness Measuring Capability - You can now test painted tanks, pipes, etc., without having to remove the paint or make corrections for the paint thickness. Ideal for measuring the effects of corrosion or erosion on tanks, pipes or any structure where access is limited to one side. 　 Operating principle: 　 Standard mode: P-E (pulse-echo) method with dual-element probes 　 Coating mode: E-E (echo-echo) method with dual-element probes
