Vacuum gauges – portable

Bullseye portable precision vacuum gauges present a new level in portable vacuum measurement. With robust gauges and rugged control units it offers unrivalled flexibility and connectivity. Bullseye Bluetooth-enabled vacuum gauges allow monitoring from mobile devices (Android or Apple), alarm settings and the documenting of vacuum data. This lightweight unit is easy to use in the field for on-site measuring but is equally useful as a laboratory or test vacuum gauge. Bullseye precision vacuum gauges combine portability, versatility as well as documenting and visual analysis capabilities all in a single instrument. The back-lit LCD display shows the vacuum level numerically or in as a graph. Settings can be easily changed with the front push button control.
