The Comparison between the UM-1D and UM-2D, is the UM-2D has a probe selection function allowing the use of different probes.  

UM-2D is a simple to use, high accuracy, hand-held Ultrasonic Thickness Gauge with the ability to measure through paint and coatings and to even 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.

There are two operating modes of UM-2D ultrasonic thickness gauge: standard mode and coating mode. The operating principle of coating mode is E-E (echo-echo). When there is coating or oil paint on the surface of the object, the net thickness of the material can be directly measured neither having to remove the coating nor calibration. The operating principle of standard mode is P-E. With the covered coating, the measurement will not be very accurate, so the coating should be removed before measuring in standard mode. The advantage of this mode is that the measuring range is relatively wide: 0.031 inch-19.685 inch (with standard probe).
