Has anyone got any new thoughts about this topic? I'm still in need of a device with which I can simply "dial in" an air pressure ... and then hold it steady for long enough to be able to adjust pots (or whatever).
It would need to be able to generate up to 1.5 Bar (1,125 mmHg) though.
I am aware of the various Drucks ... but would prefer something a bit more ... er, cheaper.
In fact I'm thinking of knocking something up myself. Something based on an old syringe pump, or whatever. As we all know, syringes themselves are all very well, but holding 1,000 mmHg steady by hand takes a bit of doing. Especially when you are trying to twiddle a pot at the same time (a two-man job, perhaps). In short, there has to be a better way!
