[USCC] Compost Respirometer Question

[Greg Evanylo]

Has anyone had any experience with the Columbus Instruments Oxymax ER 
(Economical Respirometer) Laboratory Model respirometer for 
determining oxygen uptake and carbon dioxide evolution for assessing 
the stability of compost and/or the mineralization of composts, 
biosolids, manures, etc.?

I'm interested in knowing if the Oxymax ER can measure O2 and CO2 
accurately and precisely enough to be useful for such analyses. 
Learning of any other experiences with this  equipment would be appreciated.

thanks in advance,
greg
