My Edwards E2M-1

Hi guys,

I have just finished a semi-repair on my tiny mech pump.
I have measured a vacuum of -993.2 mm/Hg with an electronic portable multimeter... (pressure, vacuum, temperature...)
It is also VERY silent !!! Good for night operation, right ?

-993.2 mm/Hg ...Is it good vacuum for a pump like this ?

Can I use a refrigeration compressor oil in it ?
(if I had trouble in finding his own)

Can also please someone explain the function of the Gas Ballast on the pump ?

ciao all
Daniele
