Hello everybody
I'm trying to make a fixed humidity chamber to test the stability in time of several items, including instrument-related parts. I'm trying to get a 75% fixed humidity environment using saturated NaCl solution as I have read on several papers. The problem is that it is not functionning as expected and I don't know why. I prepared an over-saturated NaCl solution and put it in a beaker inside a desiccator along with a calibrated thermohydrometer. The fact is that it never read 75% and instead it is reading a humidity very close to that of the environment outside the desiccator. See attached images for more details.
Any help most welcomed
