Just purchased an Instrutech Hornet Ion Vacuum Gauge. ~$900.
I chose to buy this to have a simple gross pressure gauge so we can begin pulling a vacuum. Sort of a sanity check. We expect the gauge to work. Without a proper gauge we are lost.
The hornet is the most simple/user friendly of the gauges I’ve explored. All in one unit, just plug it in and go. I think that’s the first major hardware I’ve purchased new!
Just waiting for nuts and bolts (literally) and some conflat gaskets to arrive, then we can pull first vacuum.
