The Panametrics-NDT™ Model 25 MULTI PLUS is an advanced ultrasonic precision thickness gage with several unique measurement capabilities. In addition to making thickness measurements on metal, plastic and many other materials with varying thickness ranges, the 25 MULTI PLUS has the ability to calculate and simultaneously display up to four separate
measurements. The Summation Mode accurately displays total thickness of selected layers.
