For long life sensors, paramagnetic are amongst the best. A couple of linx:

Then there are companies with standard electrochem cells, for example http://www.gmiuk.com/

Echem will be less expensive and well suited to 1% to 21% O2. Paramagnetic will be better bellow 1%.

If your just after a basic meter then some of the diving gas analysis units will be in the range of $100 to $500

Richard,

Also look into the MAP 9000 from PBI-Dansensor out of Denmark

http://www.pbi-dansensor.com/content.asp?siteID=1&pageID=91.

It has worked well for me - no cell to trouble with.

Subject: [TN] Oxygen sensor

Can anyone recommend a good oxygen sensor that can be used to verify the level of a nitrogen blanket? I am looking for one that
can be used to verify the oxygen percentage inside of the reflow oven, or on a rework station, or within a nitrogen box used for
storage of components.
Thanks for any responses.
