The Navac NMV1 Micron Vacuum Gauge for HVAC is a lightweight, easy-to-carry solution to accurate vacuum measurement. This Navac micron gauge uses the Pirani high-precision vacuum sensor to precisely measure vacuum levels. Its large digital display affords a comprehensive view of vacuum conditions. The NMV1 vacuum gauge includes a built-in alert system that will buzz when reaching a preset vacuum level, as well as when the vacuum level decreases from the established preset, buzzing rapidly and flashing the backlight to warn of leaks. This gauge may be small, but it stands up to any test. As NAVAC always says, “Leading Technology, Superior Quality, Best Experience. Empowering you to work smarter!”
