Dopers, I need your help! At work, we are looking for a device that will measure the concentration of oxygen coming out of an oxygen concentrator. My boss used to have such a beast, but cannot remember exactly what it was called. Also, it is nothing fancy - that is all it does. Can anyone help?

It’s called an ‘Oxygen Analyzer’.

According to his web site, my buddy Ron has a couple of used analyzers available – you’d probably have to buy new cells and batteries. Ron should be able to help you source cells, and acquaint you with operation of the unit.

He’s at [Best Use](http://www.bestuse.com).
