Power Tested Pfeiffer Ultra High Vacuum Prisma QME200 PTM28505 QMA200 PTM25252 Residual Gas Analyzer RGA Compact Quadrupole Mass Spectrometer QMS200 2.75" CF DN35CF Conflat Flange
This is an older model RGA from Pfeiffer. We tested it for power (seen in the 2nd photo). It powers on and the green "ready" and 24v power lights illuminate. The electronics cooling fan spins up. We did not test it beyond that. It was removed directly from a Pfeiffer turbo pumping station, and the lines all look very clean inside. Was likely used for leak testing or light gas analysis in its past life.
Used, see photos. Comes with both the electronics head, QME 200 , and UHV analysis part, QMA 200 . This makes a complete QMS 200 system, except for software and a control computer which will still need to be put together to operate this instrument.
Comes with the 2.75" CF straight nipple installed that can be seen in all the photos. We also installed a 2.75" CF tee on the end with dust caps to keep it free from dust until shipping, that can be seen in a couple of the photos but it will be removed before shipping and is not included in the purchase. The CF flanges on the analyzer and on the straight nipple are in great shape and hold UHV.
