UDT-40- precision thickness gauge with A-scan

thickness gauge UDT-40Precision, not having analogues of Russia, universal ultrasonic thickness gauge with high reliability of the testing. Presence A –scan excludes such typical mistakes at measurement of thickness as doubling of indications, and B-scan allows observing a structure of a bottom of a product. Thickness gauge realizes various ways of the testing of thickness - measurement of time on transition through "zero", measurement of time between signals, and also frequency and correlation methods of measurement.
Presence of the built in contours of the coordination, adjustable width of a pulse and three electric damping allows to use for measurement any transducers with frequencies from 0,5 up to 15 MHz, both single element and dual type.
