Multi-Echo Ultrasonic Thickness Gauge(UM-3)

The multi-echo is used to enhance the accuracy with the resolution of 0.0001 and the low limit of 0.012

Product Name:Ultrasonic Thickness Gauge(UM-3)
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 0.0001’’ and the low limit of 0.012’’. There are two operating modes of M-3 ultrasonic thickness gauge: I-E (interface-echo) mode and E-E mode. The measuring range of I-E mode is 0.059’’-0.709’’, while the measuring range of E-E mode is 0.012’’-0.394’’.
