Model VE2

The Model VE2 is a popular Mass Extraction instrument with an additional built-in quick fill circuit for higher throughput, handling medium sized parts with leak tightness from 1X10-4 sccs with AIR. It is offered for industrial applications as well as aseptic and cleanroom applications (stainless steel). Its graphical display, real time signature graphs, and touch screen make it very user friendly without risking the integrity of the test set up. It can be assigned an IP address enabling interface through your LAN.
