Leybold Inficon Quadrex 200 Residual Gas Analyzer Model# 901-002-G1 w/ ANALOG card! Here you go. There are Quadrex 200's out there, but none of them with the Analog card/hook up. I am not going to lie to you, this unit has seen some use, but it is ready for more! We were able to power this unit on, but we got the "cable error" message, which probably means that we don't have any of the other attachments hooked up to this (which we are not equipped to do). But please understand the "Cable error" is for you to determine what this means and how it affects its' use. As seen, this unit looks good on the inside. Unit does not come with any cords or attachments. Will ship international. please ask questions. Please look at pictures.
