I have one of those "air powered vacuum pumps" (which in reality is just a
venturi), similar to
http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=96677

Then I took a Mason (canning) jar and soldered two pieces of 1/4" soft
copper tubing to the lid.  Add some tubing, and it makes a small, explosion
proof, vacuum cleaner.  The pump won't handle much volume, but you could
probably use 3/8" line instead of 1/4" if necessary.

Thin wall brass tubing from the hobby store makes a good probe.
