Overview
The BluVac Micro is an excellent A/C micron vacuum gauge that has five selectable vacuum readings: Microns, Pascals, mBar, Torr, and mmHg. It can even be operated in freezing temperatures but please note that AccuTools does recommend the use of Lithium batteries for low temperature operation.
The battery life of this vacuum gauge is estimated to be up to 100 hours and can be user calibrated following the simple procedure located in the owners manual. A Calibration Self-Test can be performed to know when the BluVac micron gauge needs calibration in three simple steps.
- Power off the BluVac+ Micro
- Expose the sensor to atmospheric pressure
- Press and hold the power button. After ~5 seconds the display will read "Good" if in calibration and "Soon" if calibration is needed.
Another nice feature of the AccuTools AC micron vacuum gauge is the display will show "-OiL-" if the sensor becomes contaminated and needs to be cleaned. As with most other digital pressure gauges a simple cleaning is easy to perform with isopropyl alcohol. If needed, detailed instructions can be found in the owners manual.

BluVac App by MeasureQuick
The BluVac app receives the data transmitted by the built-in Bluetooth on the BluVac+ Micro and easily gives you readings for the system. The convenient graphs shows you how the vacuum is progressing and shows you any leaks or problems visually. You can easily save recordings and generate reports with the graphs showing the complete vacuum process.
