:lilhelp:My inficon Pilot Plus digital vacuum gauge has been an excellent tool for me against the supco bg64. No complainments at all but suddenly it started to cause me a shade of doubts. IĻve made some comparison proofs against other micron gauges and it turned out it is working fine but doesnīt return to ATM or 760,000 microns immedietly when it is disconnected from that deep vacuum and I have to wait for a little while after I see it displays 760,000 Microns.
I guess its pirani sensor got dirty but I donīt know if I can clean it as other digital vaccuum gauges or, for better results, sending my Pilot Plus to Inficon repair Service.

Don't work in AC but apparently there is a filter that can be replaced (not cleaned), and you can call Inficon for advice if that does not help (just Google Inficon). If you search in this site for pirani you'll find some other info, like this thread http://hvac-talk.com/vbb/showthread.php?t=756352&highlight=pirani . The 99% isopropyl alcohol may be OK, but I'd want to verify that first...
Hope this is a bit of help...

Yeah, itīs a big help for me... I forgot to say that Iīve changed the filters and it still works the same way I mentioned. Last thing to do is Inficon advice but not to mention the long waiting and patience till they receive my calls and e-mails...

Good morning. I have been following your thread and I believe we can help you. You can use isopropyl alcohol (70% or greater) to clean the Pilot plus, but you have to remove the filter first. Just simply put a little in (~1tablespoon) swish it around and discard of the used alcohol, then let the unit sit for at least 6 hours to let the remaining alcohol evaporate before replacing the filter and connection. If you have any further questions or need any additional information, please feel free to give us a call at our phone number located in our profile. Thank you!

Now I am impressed with this kind of customer service, not only the answer but exactly how to do it! if I ever need a new vacuum gauge, I know whose customer service to use as the measuring stick...
