Absolute Vacuum Test & Calibration Stand

There are a lot of absolute pressure calibrators available. Try Ruska, DHI, Druck for instance.

I bought a Vacuubrand Digital Gauge and controller. DV2000. My problem is getting my connections secure so I can bench test\calibrate Smart Transmitters. Down to .5 mmHg Absolute. I am unable to buy and put together a good test stand. If there was a company that pre-fab'd some kind of test stand that would help a bunch.
