µBluVac is ideal for budget-conscious technicians without sacrificing performance.


AccuTools® µBluVac Digital Micron Gauge represents a breakthrough in economical vacuum measurement. Small and light enough to fit in a shirt pocket, the µBluVac is a full-featured basic micron gauge that utilizes our famous patented BluVac technology to provide the highest accuracy and dependability at the lowest possible cost.The µBluVac accurately and quickly measures vacuum in Microns, Pascals, Millibar, mmHg, and Torr with a resolution down to 1 micron. Sporting a large back-lit display, the µBluVac operates for up to 100 hours on two AAA batteries and at temperatures below freezing.

Possessing the same accuracy and reliability of the standard BluVac gauge, the µBluVac is ideal for budget-conscious technicians without sacrificing performance.

Innovative Oil Sensor and Self-Diagnostics ensure accuracy. The BluVac series of Micron Gauges are the only field-calibratable vacuum gauges that require no special equipment for calibration.
