The MiniTest 420 is a basic straight forward ultrasonic thickness testing gauge for simple quick measurements. The MiniTest 420 incorporates a calibration block for zero adjustments and quick calibration.
Sturdy and accurate ultrasonic thickness gauge based on the ultrasonic pulse run-time method.
6 ultrasonic probes with frequencies ranging between 2 and 10 MHz in different designs offer a broad spectrum of applications and thickness measurements ranging from 0.65 mm to 500 mm. A high temperature ultrasonic probe is also available, designed for measurement of hot materials with temperatures of up to 350 °C.
Uninterrupted scanning of a part for thinning is possible at the minimum mode.
