AccuTools® BluVac Digital Vacuum Gauge

The AccuTools® BluVac Digital Vacuum Gauge is a state-of-the-art digital vacuum gauge utilizing patent-pending technology to deliver the highest accuracy and resolution on the market.


Loaded with features the BluVac digital vacuum gauge is one of the most innovative products that TruTech Tools has seen or tested in a digital micron gauge! Problems with oil contamination, field calibration, and work flow have all been addressed. At 0.1 micron resolution you can easily see if the vacuum pump is gaining ground, if the oil needs changed, and when the gauge is isolated the decay of the vacuum and the ultimate system pressure. Because of the resolution of the BluVac, we highly recommend you use vacuum rated core tools and hoses. All hoses leak, and at .1 micron resolution that will be very apparent. Operating for up to 300 hours on a single 9V alkaline battery, the BluVac sports a large 1/2" numeric display and a bright blue backlight. The BluVac measures from 0 to 25,000 microns with 0.1 micron resolution below 10,000 microns.

Accurately measures vacuum down to 10 degrees F with lithium batteries making it ideal for refrigeration applications.

Innovative Oil Sensor and Self-Diagnostics ensure accuracy. The BluVac is the only field-calibratable vacuum gauge that requires no special equipment for calibration.

Use the TruTech Tools RapidVac Kit for ridiculously quick evacuation times. The use of this kit with the BluVac gauge assures fast and accurate evacuation results!

Recommended Accessories

We recommend the use of vacuum rated core tools and a brass coupler with the BlueVac and BluVac LTE. All hoses leak to some degree. Using a brass coupling and Nylog assembly fluid will prevent leaks at the core tools and fittings that may otherwise be problematic.

A note on temperature response:

If powered up when not connected to a system, the sensor does not *immediately* reflect room temperature.The temperature displayed is the temperature of the metal vacuum port, hence it takes time for the port temperature to change to ambient conditions because of it's thermal mass. This is intentional aspect of the design, intended for accuracy in use while connected to a system, as the gas inside the port maintains the temperature of the port, not the surrounding ambient.

Bluvac micron gage

By: Adrian (Yuma, Arizona) on 10/7/2013

Great micron gage, nice features, some what fragile, great customer service from manufacturer.highly recommend,


By: Lucas Tyssowski (Baltimore, Maryland) on 1/2/2013

This is a great tool. I've used similar brands in the past but did not trust their accuracy. I began using this tool last year. All of our techs who have used this gauge also like it. I will be buying more for the company to use in order to insure that our work is top quality and always dry. There is little doubt as to what's going on when using this tool during evacuations.
