wiz I thought you went back to using the Yellow Jacket. Didn't you hate the BluVac operation so much he took it back?
From my experiences with BluVac and testing it I came to the conclusion every other micron micron gauge out there was lying to me no matter how much I liked seeing the other reading............ or disliked the BluVac reading. People here have tested the BluVac against the super accurate bench type micron gauges not meant for the field and agree with it.
IMO It would be impractical or nearly impossible to follow every school taught evacuation rule when using a BluVac but for me having the consistency of the reading and knowing it was right was most important. What you do with the accurate reading needs to be a professional judgment call IMO. People might not like to here it but changing filter driers and knowing the sound of your vacuum pump has worked for me for years. After using a BluVac and other micron gauges it has only firmed up my belief with the suggested service and evacuation rules that guys not following any of them are having system/failure problems. Owning a, none or the best micron gauge is only part of or service procedures and don't have much to do with success in the field
