 Chamber has some very simple adaptive manifold connectors it should be fairly easy to replicate/customise, as well as add more custom ports as need be.

+Have collected a Pirani/Penning gauge controller. Purchased from ebay for £5, plus packet of chips for ride to collection. Edwards Model 4, approximate age of existing gauge heads. Should be compatible. Supports two pirani and one penning head. Not rack/panel-mount, but should do the job very nicely. Will need compatible mains plug.
+Likewise purchased some mixed Speedivac fittings (£11 including postage) that should make building up the vacuum pipework a lot nicer (avoiding using the home-made joints is a bonus).
+Also donated a water-flow meter. Currently runs on 24v relay, but has fitting for hall-sensor control, so suggest gutting of stock electronics and wiring directly into control systems.
