Conventional UT

Test Wizard

Setup wizard will help users configure the professional operation process, enabling more professional testing.


Display A-Scan echo in imaging mode, to achieve more intuitive test results for easy observation and analysis.

DAC Curve

Easier, more convenient, flaw evaluation


Auto created by taking a known flat-bottom hole or large flat-bottom echo for reference.

Weld Simulation

Simulates the weld shape and uses the dynamic beam tracking function to assist the user to quickly determine the location of flaws in the weld.

Probe Spectral Analysis

The probe waveform, spectrum and center frequency of the probe can be measured precisely by capturing echoes.

Flat Weld Testing

Angle Weld Testing


Thickness Measurement


Based on time interval or encoder, you can display the measurement readings in a B-mode image.

Data Set Management

Measurements are recorded and displayed in grids.

Through-coating Management

After setting the coating velocity, through-coating thickness and coating-thickness can be displayed at the same time.

TDG (Time Distance Gain Curve)

It can be used for compensating the loss of echo amplitude due to propagation of sound path.

TempComp Function

When there is a temperature difference between the calibration block and the detected workpiece, this can be used for temperature compensation.

V-PATH Function

All the original dual element probes have a set of default V-PATH calibration curves. Users can make a set of UserVpath curves for a specific probe.
