The Yellow Jacket® Omni™ Digital Vacuum Gauge is easy-to-use, compact, rugged, and offers several features. Made with high-impact, glass reinforced housing, it survives moisture and accidental drops or attachment to a high pressure line. The easy-to-clean vacuum sensor handles 450 psi positive pressure and reads several units of vacuum (microns, millibar, Torr, and Pascal). The user interface is intuitive — turn it on and it’s ready to use with default settings. An audio and visual signal is sent when target vacuum level is reached.
