Digital Lab Measuring Instruments Flaw Detector Ultrasonic High Precise Positioning

Function & Feature

With high-precise positioning, it meets requirements of close and distant detection;

Small blind near-field allows the detection of small diameter, thin-walled tube;

Automatic calibration: with one button automatic calibration, convenient operation, automatically
testing the "zero", "K value", "forward" of the probe and "speed of sound" of the materials;

Auto display the location of flaw echo (depth d, level p, distance s, amplitude, equivalent dB,
aperture value);

Free switch to three kinds of standards (depth d, level p, distance s);

Auto-gain, return envelope, peak memory function improves detection efficiency;

φ value calculation: forging straight probe testing, identifying the highest wave of defects, automatic
conversing aperture value and calculating the large flat;

100 independent testing channels (expandable), you can freely enter and store any industrial testing
standard, do field detection without test block;

Freely store and playback 500 A-scan wave forms and data;

DAC and AVG are automatically formed, without restriction of sub-sampling points, and can be corrected

and compensated.

13 built-in testing standards can be used;

You can freely enter any industrial standards;

The width and intensity of launch pulse are adjustable;

It can connect to the computer, realizing data management, and exporting inspection reports of Excel
format with A4 paper ;

With the durable shell,oil-proof, water-proof and dust-proof;

26 million colors ultra-bright display, adjustable brightness, suitable for both intense and low light working environment;

Battery with a good performance of safety and environment-friendly, can work for 10 hours.

Time records: track and store records of testing date, time;

With power outage protection, stored data will not be lost;

Testing parameters can be automatically tested or preset;

With digital suppression, no effects for the gain and linearity;

Gain Compensation: Correcting dB attenuation caused by surface roughness, surface curvature,
distant-testing of thick piece and other factors;

Two input methods: Angle and K values
