If your hygrometer is off by -5% RH, then the 50% reading that you see in your box will actually be 55%, since most digital hygrometers are accurate to +/-5% RH. :think: At this RH, it might just be conducive for fungus to grow.
i'm glad to hear tat, it sure takes some time for me to get into 42%...
at 1st is 54%,
after some tuning, became 51%,
after some tuning, became 31%
after some tuning, became 37%
after some tuning, became 41%
finally after some tuning, became 42%
I have a digital cabi, with digital RH setting. What i found out was:
I set my cabi to RH 45%. When the cabi shows that it reached 45%, my another xtra analog hygrometer which is inside show RH 55%
I changed the analog hygrometer position to another level in my cabi, and it will stay at RH 65& for the rest of the time.
This experiment shows that the RH in cabi is not fixed throughout?
Anyone who tried this before pls share...
In my 90L 4-tray dry cab, the hygrometer on my uppermost tray often has readings 2% lower than the one at the lowest tray. Even if I switch their position, the end result will still be the same. It goes to show nothing is wrong with the digital hygrometers.
