Product Introduction
Shandong China Coal Portable digital ultrasonic flaw detector
Feature:
Color liquid crystal display with high resolution , the real-time measurement system of echo dynamic;  
Simple button, and the combination of touch screen and button provides more convenient one-handed operation pattern for users;
Users can change battery and memory cars’ design, to avoid future trouble and worry, keeping equipments’ long-lasting work;
The operation of USB is available. The real-time data backup and recovery; the operators do not need to be afraid of deleting their data; instead they will be carried with you;
With its function of real-time screen alarm and analog output. Its two independent measuring gates are applied to dealing with wider ranges;
The optional frequency range from 400 kHz to 20MHz matches probe to reach the optimum performance;
With function of flexible configurable measuring result. The needed important measuring information is chosen by the operator;
Abundant real-time operation’s hint and practical status display largely reduce the difficulty in first learning equipments and make it is easy to understand the equipment operation;
Various choices of color profile are provided for operators to display topics and controlling brightness, adapting operating requirement in different environment;  
Guided probe calibration and curve making make easy calibration;
Being able to store infinite multi-group DAC/AVG curves without trouble of channel number; the curve can callout, introduce and derive backup;  
Apart from offering two basic evaluation patterns, DAC,AVG(DGS), it provides up to nine kinds of evaluative criteria usually seen at home and broad. Besides, the corresponding standard test block and inspection level are set inside to ensure the safe calibration;
Offering various high-grade supplementary evaluations and measuring means, like depth compensation, half span of color and equivalent curve measurement, escaping test task from a variety of artificial judgment and calculation. It will be more relaxed;
AT80’s adjusting function of auto-gain with one click can adjust gain automatically to set echo-peak at the 80% of full screen, quickly up to users’ requirements;  
The envelope function of peak can clearly reflect the location where the highest echo (flaw) occurs during the scanning;
With the function of continuously storing A scanning image (that is kinescope recording) and real-time playback. It can continuously record test procedure for up to five hours;
