Bullseye precision portable vacuum gauges

Remote vacuum monitoring made easy...

Portable, practical, precise - stand-alone or with Bluetooth...

Bullseye portable precision vacuum gauges give a new level in portable vacuum measurement. With robust gauges and rugged control units they offer unrivalled flexibility and connectivity. Bullseye gauges are Bluetooth-enabled allowing monitoring from mobile devices (Android or Apple). These gauges are lightweight and easy to use in the field for on-site measuring, but is equally useful as laboratory or test vacuum gauges.
Bullseye precision gauges combine portability, versatility, documenting and visual analysis in one instrument. A back-lit LCD display shows vacuum levels either numerically or as a graph.

Specifications of Bullseye gauges and how to use them

The Bullseye vacuum gauge is the ideal tool for service engineers. With its small footprint, long coiled cord and magnetic hook it can easily be fixed in place leaving your hands free for vacuum measurement.

Conversion between units
Bullseye gauges include instant conversion between 12 different vacuum units - ideal if vacuum performance needs to be checked on older or foreign equipment. Units converted are: Torr, mbar, bar, kPa, Pa, PSI, inches of Hg, mm Hg, millitorr, microns, inches of H20, mm of H2O.

Using on stationary equipment
On stationary vacuum equipment, the Bullseye Bluetooth enabled precision gauge is ideal for replacing older equipment and gives instant remote monitoring and data storage on mobile devices. In manufacturing environments, technicians can instantly check and document performance of vacuum assemblies and equipment.
