Dependencies and characterisics for Figaro gas sensors

Hi guys!

I'm about to use Figaro sensors (TGS 4161 for CO2 and TGS 2442 for CO) in an important project at school and I need more precise data on how to calculate the actual concentration they measure.

In their datasheets, there are two small charts that show the dependencies, just that not all the parameters are included and it would be sooo much better to have all the values in a table, rather than guessing some of them of a picture.

So please if someone used them before and has that information, send it over!

Thanks a lot!

P.S. Oh, and asking the manufacturer would not be an option because their rep in my country has really high prices so I'll have to go to another supplier. Complicated story...
