GE USIP 20 (USIP-20)

The USIP 20 systems flaw detector - High performance and multichannel

Four flaw gates, each with two thresholds, give complete versatility of test configuration. Floppy and hard disk recording media allow for ease of setup storage and recall, and for transfer of parameters from instrument to instrument. 

Control menus are displayed on a large, bright LCD and adjustments easily made through both dedicated and variable function controls. "Ease of use" has been our key phrase in the development of the USIP 20.Each control menu is displayed using a devoted function key, so that no standard operating menu is further than a single button push away.
