How do you measure the percent of oxygen?

Thanks

You have to have a weather station that measures the percent of oxygen. I know Altronics has them as an option.

I mostly look at the humidity and the barometer to make comparisons. The 327 engine that I am running is much more difficult to dial than the 350 that I have. Must have something to do with the shorter stroke.
