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.
