Accuracy of salt test calibration

[Drez]

I leave mine for 24 hours. Most of the time after 10 to 12 hours it will read 75%.

I don't know if the humi would work cause I don't really have any but I don't see why it wouldn't as long as the pack is working like it should as stated above.

I know it works with beads like I said above I spot check all of mine every 2 or 3 months with the beads.
