MiniTest 400


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 (only in the case of MiniTest 430 and 440).

Uninterrupted scanning of a part for thinning is possible at the minimum mode.

Three variants of the coating thickness gauge Elektophysik MiniTest 400 are available:

  • Elektrophysik MiniTest 420
    Sturdy and economically priced basic model with memory, USB interface and automatic probe-calibration detection. Standard and minimum measurement modes are available.
  • Elektrophysik MiniTest 430 – With integrated memory for 10 groups each with maximum 500 measuring values and USB interface. Besides the MiniTest 420 model, the differential, alarm and scanning measuring modes are also available.
  • Elektrophysik MiniTest 440 – High-end device with integrated memory for 10 groups each with a maximum capacity of 500 measuring values, USB interface and 5 measuring modes; connecting echo-echo probes is possible.
