The UFD M620C is an advanced digital ultrasonic flaw detector featuring a multi-color TFT LCD (320 x 240 pixels) and a host of new features to meet challenging inspection requirements. It combines powerful flaw detection and measurement capabilities, extensive data storage, and the ability to transfer detailed inspection data to the PC via its high-speed USB port.

The instrument incorporates many advanced signal processing features including a 15MHz RF bandwidth to permit testing of thin materials, narrowband filters to improve signal to noise in high gain applications, a spike pulser for applications requiring higher frequencies, and a tunable square wave pulser to optimize penetration on thick or highly attenuating materials.
The instrument can be widely used in locating and sizing hidden cracks, voids, disbands, and similar discontinuities in welds, forgings, billets, axles, shafts, tanks and pressure vessels, turbines, and structural components.

Optional accessories

Ultrasonic probes:
We offer wide assortment of ultrasonic probes to enable a professional measurement.
If a standard probe cannot be used for your tests, you can order a custom-made probe from us.

Ultrasonic probes

Wzorzec W-3
International W-1 standard

W-1 standard
W-1 standard is used to control the measuring device parameters: gain, scaling, time base for longitudinal or transverse waves; it is also used to check whether the parameters configured were not changed during tests. W-1 standard enables controlling the reflection angle of skew probes, the energy of device-universal probe circuit, and also examining the universal probe resolution, universal and skew probe sensitivity setting, as well as approximate adjustment of a dead zone.

W-2 standard for welded joint tests

W-2 standard

The W-2 standard is used to graduate the time base for transverse wave and determining the energy of skewed probes

The W-3 stepped standard

W-3 standard
The W-3 standard is used for graduating the time base for longitudinal waves in order to test thickness of materials from 2 mm to 10 mm.
