LS2789 series transformer comprehensive tester is a new generation of transformer tester. This series of testers are the new wisdom of the project team with more than 10 years of research and development, sales and service experience in the transformer testing industry. In meeting the requirements of high stability, achieving the ultimate measurement speed will once again promote the progress of the entire transformer testing industry.
This series of instruments uses a 7-inch true color LCD screen with 800×480 resolution to achieve full screen display of all parameters. A variety of operating interfaces are available to adapt to different user preferences. Transformer scan boxes are available from 20Pin to 192Pin to meet the needs of various transformer tests.
