Anyone have a digital vacuum gauge they like? Needs to monitor down in the 5-10 mTorr range for roughing pumps. The only one the lab has doesn't do precision < 1 Torr, which is obviously a problem when a roughing pump with issues might still be pulling down to 100 mTorr.

The one the technician had for the lyophilizer was a digivac 100h, which is maybe overkill for us. Their "bullseye precision gauge" seems like an option though. I'm open to other brands (the one we have that won't work for this is VWR), etc, it just needs a good adapter on the end to fit to standard size tubing (minimum inner diameter of 7 mm, but most of the direct connections to the vac pump are probably > 1 cm).
