The e-Vision 2 EV2-220-000FT is one of a new range of residual gas analysis products, from MKS Instruments, designed to meet all the traditional requirements for an RGA sensor but with data collection at speeds unachievable with previous generation technologies. It has a Multichannel Plate Dual Detector with a mass range of 1-200 amu and an open ion source. e-Vision 2 RGA is designed to provide maximum value for money, collecting data at millisecond speeds per data point even when measuring data over the full dynamic range of the RGA.
