Name: LFD820 Ultrasonic Flaw Detector
Brand: Beijing Lanetech Square Co., Ltd.

Functions of LFD820 Ultrasonic Flaw Detector

Automated display precise flaw location(Depth d、level p、distance s、 amplitude sz dB、ф).

Flaw sizing: Automatic flaw sizing using AVG/AVG or DAC, speeds reporting of defect acceptance or rejection.

Automated calibration of transducer Zero-point, Angles, Front edge and material Velocity .

Convenient to make and use DAC and AVG to evaluate the echo, the curve can be modified and compensated.

Connectting U-disk，the unit can get unlimited memory,PDF reports out put and Upadte system.

Automated make video of test process and play; use upan，the length of video is unlimited.
