Return of the diy_EGOmeter (YES, it's finally ALIVE!!)

[Gus Cameron]

Just to change the subject a little bit....
Can anyone tell me how lambda/AF ratio relates to the true % oxygen?  Has
anyone ever heard of anyone using these ion pump sensors for non-automotive
applications?  The reason I ask is that in the course of my work (I'm a
biochemist, ex-biochemical engineer) I use mass specs and paramagnetic O2
meters to measure %O2 from athletes lungs.  These gizmos are v. accurate
but you dont wanna know the cost, and the response time / reliability
isnt always what we would like (and we can only afford a couple of them).
Maybe a EGO sensor is what we need?  Thought, truth be told, these athletes
have enough problems with their egos as it is, heh heh.
TIA,
