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
