Vacuum Bottle Testing – Have vacuum breakers approaching 20 years, even 30 years old? Concerned about their condition? Until recently, “go/no-go” vacuum integrity tests using an AC Hipot was the only field test available. New technology has now made it possible to not only analyze the condition of vacuum breakers with more certainty, but also to predict their remaining useful life.
