Gates Two fully independent gates offer a range of measurement options for signal height or distance using peak triggering. The echo-to-echo mode allows accurate gate positioning for signals which are extremely close together. High Accuracy ultrasonic flaw detector machine Gate Start: Variable over entire displayed range Gate Width: Variable from Gate Start to end of displayed range Gate Height: Variable from 0 to 99% Full Screen Height Alarms: Threshold positive/negative with LED Flash.

High precision ultrasonic flaw detectors Memory The instrument has a built-in large-capacity memory, and data and files will not be lost due to power failure of the instrument. Memory of 500 channel files to store calibration setups and probe parameter. Memory of 1000 wave report files to store A-Scan wave and settings. All the files can be stored, recalled and cleared. The channel settings and report files can be exported via U disk, and the information can also be stored in unlimited amounts via USB memory.

Video Recorder Video Recorder is useful in many situations, it is very convenient for those who want to analyze the probing activities later. The instrument can record the test process and save it as a video file, which can be played back through the instrument or special software. It supports up to 10 video files, and each video file can be up to 5 minutes long. If you choose to save the video file to the U disk, the number and duration of the video file will not be limited. Recording and replaying the testing process provides great convenience for future study and analysis of flaw detection. Video playback supports pause, fast forward, fast rewind, and stop functions.
