Thanks for finding the info, Darren. That makes sense with what I saw; since it's a two-way pack, they are going to sell with the salt solution over saturated so it still has the capability of absorbing some excess humidity while maintaining the setpoint RH. If they sell it at a charged/total weight of 8g, they get crunchy around 3.3g, this means there is about 4.7g of water in there. When over charged, I saw it start hitting the target RH once it dropped to about 9.5g in weight when placed into a dry bag, so that means it has the ability to absorb approximately an additional 30% water, which is reasonable.

My pleasure!

If all these values are fixed (RH setpoint of the RO membrane, etc.), can we graph out how long a depleted pack must soak to hit the target weight?

Maybe.

There are some things we don't know about these packs, like what the transfer rate is through the membrane. Also you have a variable for how dried out the pack really is when you start and water temperature might also be a variable.

I suppose I can take a few dried out packs and toss them in water, then periodically pull them out to weigh them. Not exactly the most scientific method, but maybe narrow the times down a little bit.

It was just a thought. You guys have done some good work and it was fun geeking-out with you. Personally, I use the sealed Tupperware method but that takes time; a quicker way would be helpful but at this point, you've done enough work. Bravo-Zulu!
