The Bullseye Precision Gauge Piezo is a Vacuum/PSI Bluetooth Gauge that provides highly accurate and reliable vacuum reading from 20 Torr to 85 PSIG and allows for remote monitoring of your pressure readings.

  • Visual Graphing: Patented digital graphing capabilities (Pumpdown graph, Autoscaling line graph, and bar graph)
  • Remote Monitoring: Enables remote monitoring and troubleshooting | Transmits vacuum information to cell phones or tablets via Bluetooth | Versatile digital rough vacuum gauge that you can monitor right from your phone or tablet (Apple ios and android) | Set low and high alarm from your phone
  • Data Capture: Communicates with the DigiVac Cloud so you can view your vacuum process and record your data | Email vacuum data for documentation or transmit vacuum data directly to the DigiVac Cloud
  • CE, CSA, UL, and RoHS

Portable and Precise 

  • Bluetooth Bullseye Piezo | Vacuum/PSI Bluetooth Gauge with hermetically sealed isolated stainless steel sensor that is ideal for applications where more precise measurement of vacuum and pressure is necessary
  • 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 (NIST certification with documentation is an available option)
  • Total range: 20 Torr to 85 PSIGSEN-775i-NPT-2.jpg
  • Most accurate range: 50 Torr to 85 PSIG
  • Accuracy: +/- 15 Torr   +/- 0.5 PSI

Graphing and Analysis
