    Product Description
    ElektroPhysik MiniTest 420 Ultrasonic Wall Thickness Gauge
    Uses Pulse-Echo Principle of Ultrasonics
    Basic Ultrasonic Thickness Gauge with adjustable calibration for a wide range of materials
    Several Transducers are optionally available including one for High Temperature materials (350 °C)
    Automatic identification of probes

    The ElektroPhysik MiniTest 420 Ultrasonic Wall Thickness Gauge 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.

    F.A.Q.


    Do Ultrasonic Thickness Gauges require any training for use?

    No. Ultrasonic Thickness Gauges are designed for simple operation and feature easy-to-use instruction manuals. We also provide technical support via telephone and/or email, and a 30-day money back guarantee.

    Are Ultrasonic Thickness Gauges calibrated at the factory?

    Yes. Ultrasonic Thickness Gauges arrive fully calibrated and ready to measure.

    Do Ultrasonic Thickness Gauges include Certificate of Calibration?

    Yes. Ultrasonic Thickness Gauges include NIST-Traceable Calibration Certificate, CE-Certified

    Can I measure the thickness of non-metallic materials like plastic and rubber with Ultrasonic Thickness Gauges?

    Yes! Ultrasonic Thickness Gauges feature several preprogrammed sound velocities for common materials.

    Can Ultrasonic Thickness Gauges measure cast/ductile iron or cast aluminum?

    Yes. Ultrasonic Thickness Gauges instruments are designed to accurately measure the wall thickness of carbon steel, aluminum, stainless steel and plastic.
