The calculated % oxygen saturation is 52.79% but if you use the saturation monogram the result is 40%. This is a big difference! Using the web calculator at http://www.hbuehrer.ch/Rechner/O2satur.html using an elevation of 500 masl I get 41.13%
I think the % saturation calculator needs checking or an explanation is required for the difference.
Salinity meter is not accurate and has been sent away for inspection.
