Need Nitrox Diver Opinions: O2 Compensation Chart

[Patti Analox]

Dear Divers,
I need your opinion on a product improvement we are entertaining here at Analox Sensor Technology: When using temp and humidity to set your starting O2 calibration (O2EII, and the ATA), Analox has always provided the following compensation chart:

We are now considering the following simplified chart:

OK, you usual suspects: I know you can just use dry tank air. I need your opinion on the two charts. As always...thanks you guys!

Happy Holidays and Safe Diving!

Looks like the lumpers are having a go at the splitters. Being in the latter group I prefer the original chart as I don't need to get out a straight edge for those border zones.

I also like the green zone which can be quickly eyeballed to see if the humidity correction is needed.

Yeah, no lines make the second one guesswork without two pieces of paper

Pardon my ignorance, but aren't most O2 sensors temp compensated electronically?

Why? The original is pretty simple as it is, and it works.

I like the first (if I don't have an air tank available).

 

[ferretchen]

I like the first, but why not provide both?

Maybe,but that would only compensate for temperature change at zero humidity.

Hotter the air,more water it can hold. Temperature compensation can not correct for that.

I've never had a problem with the first one- the second one would be more readable with grid lines on it.

Stick with the original...if it ain't broke, don't fix it!
