Introduction
The UM-1D is a simple to use, high accuracy, hand-held Ultrasonic Thickness Gauge with the ability to measure throughpaint and coatings and even to eliminate the thickness of the paint or coating. You can now test painted tanks, pipes, etc., without needing to remove the paint or make corrections for the paint thickness.
