The DigiVac Bullseye Precision Gauge with Bluetooth is the world’s first wireless vacuum gauge featuring one-of-a-kind patented vacuum graphing and DigiVac’s ‘Vacuum Gauge’ app

  • Versatile wireless vacuum gauge that you can monitor right from your phone or tablet (Apple ios and android)
  • Enables remote monitoring and troubleshooting
  • Set low and high alarm from your phone
  • Email vacuum data to document leaks, baseline pressure or pump-downs
  • Use battery power or standard microB-USB power
  • Choose standard Thermocouple Plus sensor or the Upgraded Agilent 531 NPT sensor (this sensor configuration is CE and RoHs compliant), or the Agilent 536 NPT sensor which includes an integrated baffle to extend the life of the sensor by helping to protect it from contamination

Portable and Precise

  • Rugged thermocouple vacuum gauge ideal for understanding: Leaks, Pump Downs, Out-gassing or Stable Systems
  • Includes a powerful magnet and kickstand to enable hands-free operation
  • Long battery life and versatility with 12 different measuring units (micron, Torr, Inches of Hg, kPa, Inches of H20, millitorr, mbar, Pa, PSIA, mm of Hg, bar, and mm of H2O)
  • Calibrated under actual vacuum against a NIST standard. If you require NIST certification with your gauge, please add the NIST certification to your order

Graphing and Analysis

  • Patented vacuum graphing displays vacuum and time data
  • Visual graphing right on the display that identifies current system status
  • Vacuum Analytics to quickly identify vacuum pressure trends
  • Graphical display for quick determination of vacuum level

Bluetooth Bullseye Gauge Applications

  • Vacuum pump testing
  • Baseline vacuum pump performance
  • Transformer dry-out
  • Schlenk line monitoring
  • Botanical oil processing
  • Distillations
  • Vacuum Process Monitoring

Companion App

  • If you have an Android device with a Version 10+, please visit this app page to download the free app.
  • If you have an Android device with a Version under 10, or an Apple device, please visit this app page to download the free app.
  • The Bullseye PC Logger dongle The Arrow enables any bluetooth Bullseye gauge (Original Bullseye, Piezo or DASH) to log data directly to a PC over a wireless bluetooth connection.
  • Target Tracker: Allows users to seamlessly capture, view and record their system performance in real time. Transmits the Bullseye’s information directly to your desktop when paired with the Arrow.
