Evaluation Test Port

Whenever a vacuum system is not performing well enough, usually as seen by a high reading on the system vacuum gauge, three scenarios are possible:

       -The pressure is too high-  Could be a leak, a bad pump, moisture in the pump oil, etc
       -The gauge is out of calibration.
       -The gauge tube has become contaminated.

Digivac can't help you if your pump is bad, your system leaks, or your oil has moisture (summer: gas ballast!) but we know what to do about gauging.

We recommend keeping a standard gauge and the valving to instantly connect it at the first sign of doubt.

The standard gauge can be any gauge you trust, and it must be kept in a safe place, out of service, with the tube it was calibrated with.

The Digivac Model 100W battery-operated gauge is excellent for this purpose. (Battery operation is nice. Chances are, the day you are wrestling with a problem you would not be in the mood to look for an extension cord!)

Access ports with tee and mini ball valve at all gauge tube locations:
