AiPO dry cabinet problem/question~

[chiewkit]

Not sure if this is normal but I bought this AiPO dry cabinet 2-3 months ago but I'm seeing difference between the control panel & my hygrometer humidity level.

Wondering if anyone have experienced this or this is normal?

Anyway, picture is worth a thousand words in this case...

Hahaha I have the same readouts too, but I tend to believe that the humidity level inside the box is not equal. Also my hydrometer is giving me conflicting result, ie on a rainy day I left it beside an open window and it was below 60%

Interesting, did you by any chance tried another hygrometer to confirm?

I'm still looking for another hygrometer now to double-confirm~

No I don't have another Hygrometer to confirm.

Bro. saw your posting sometime back on the Aipo reading diff. I am also facing the same problem, but its the reverse of your, meaning i set aipo 45%, my digital hygrometer show 52%. Proling send me a new adapter, but the reading the same. Just wondering how you resolve your pblm. I have sent my unit back to proling for warranty claim. previously i own a digicab dry cabinet i dont have such problem. diff maybe on 3%.
thanks

Found this article on how to test the accuracy of your hygrometer. Hope this is helpful in troubleshooting you issues. I think the test portion applies to digital hygrometer as well.

thanks Hanuman. I have did the salt test on my digital meter. It was read @ 75%. so i guess is pretty accurate. As for Aipo cabinet thingy i place the digital meter inside an empty cabinet and set the lcd setting on the aipo to 45%.
However after 3 hrs the setting on the Aipo drop to 45% BUT my digital meter shown otherwise 52%. I let it sat for another 3 days, still the same. Now i dont know which reading should i trust?

The analog hygrometer version is more reliable, plus no need to worry about battery. Try not to go below 40-45RH as the rubber grip on the lenses/body will dry out and become brittle in the long term.

thanks mrmarks. pblm now is that we got 2 readings. which one to trust/believe?

The question is which has better calibration. If you leave both exposed to external humidity, what readings do you get?
