HZ-ATU601 Digital Ultrasonic Flaw Detector

Overview

This instrument is a collection of portable and fully-digital ultrasonic flaw detector. The two models in the series–high version and low version–all have the capacity to detect, localize and evaluate various defects in metals with rapidity and precision. Particularly, it is highly effective in the detection of welds, cracks, inclusions, and metal porosity in a non-destructive manner that is suitable for laboratory or project site environments. The detector’s wide variety of applications can be highly useful for defect detection and quality control in manufacturing, steel metallurgy, metal processing and chemical engineering, among other industries. Moreover, it can also be widely used for in-service safety inspections and live assessments in aircraft, railway and traffic industries, as well as boiler and pressure vessels.

Features

The Digital Ultrasonic Flaw Detector offers high speed, high accuracy, high efficiency, high reliability, and real-time operation in a digital interface. The detector contains the most up-to-date technology and has the following features:

User-oriented interface with a multi-function shortcuts, menu operation and a rotating navigation wheel.

5.7-inch TFT color screen with adjustable color and bright settings.

A small and light portable battery that can be charged anytime for use in any environment.

Multi-channel testing with the option to save channels.

Large capacity for waveform storage and the ability to load waveforms.

The capacity to record and store high-speed videos.

Automatic readings capture with moving gates.

Adjust the gain conveniently using gain subtraction shortcuts (users can also access the preset parameters with one key).

Automatic calibration for various probe parameters.

No order limit for point in DAC and AVG curves.

Fully adjustable pulse transmission (amplitudes and widths) with built-in support to block pulses and transmit sharp pulses.

Impedance matching for different requirements of sensitivity and resolution.

Four work modes: normal probe, angle probe, dual-crystal straight probe and transmission probe.

Receive and amplify signals:

Real-time sample: high speed ADC, wave detail fully displayed.

Rectification: full, positive, negative, reflective.

Gate: dual-gate, support time gate and sound path gate, echo capture automatically.

Gain: Multi-grade adjustable, basic gain, scan gain, compensation gain, support locked gain and auto gain;

Defect location: values for horizontal value (L), depth (H) and sound path (S).

Defect quantitative analysis: flexible display according to an adjustable reference.

Defect qualitative analysis: real-time estimates and judgements of envelope waveform.

Curved surface correction: automatic correction and conversion of curved surfaces (only high version)

Broadening function: user-adjustable ability to broaden the waveform selection.

Echo code: different echoes distinguished by different colors (only high version)
