Re: NEON- more on ovens



In a message dated 96-09-06 11:20:32 EDT, you write:

<< The operator can check this pressure by observing the colour of
 the discharge of a spark plug (pig hunter).....

spark plug, (pig hunter).....   ????





<<the pressure was low enough to extinguish a geisler discharge...

Is this a small tube you have hooked up to your manifold for observing the
vaccuum by the discharge or lack of it?
If so, please describe it.


I think I know what you mean, but please elaborate.

Thanking you in advance,

Jon
