General information: Single-crystal delayed probe is employed by UM-3 precise ultrasonic thickness gauge. The multi-echo is used to enhance the accuracy with the resolution of 0.0001in and the low limit of 0.012in. There are two operating modes of UM-3 ultrasonic thickness gauge: I-E (interface-echo) mode and E-E mode. The measuring range of I-E mode is 0.059in-0.709in, while the measuring range of E-E mode is 0.012in-0.394in.
The operating principle of UM-3 is: THICKNESS= (VELOCITY × TIME)/n
Note: n is the number of times of the echo. The more echoes, the higher the accuracy.
