Thru-Paint Mode (E-E) eliminates the Coating and only measures Wall Thickness
The ElektroPhysik MiniTest 440 Ultrasonic Wall Thickness Gauge is a 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.
The device is equipped for automatic detection of the intelligent ultrasonic probes and re-calibration is not required upon switching probes. The calibration data of the sensor is saved in the probe.
Uninterrupted scanning of a part for thinning is possible at the minimum mode.
