<p>[QUOTE="jaceravone, post: 1930730, member: 9474"]For years I have used an Caliber III Hygrometer to monitor the temp and humidity in my safe. It was regarded as a very good hygrometer for the price. It has worked fine, but I have always wondered on how accurate it really was. Recently, I had a deal that I could not pass up on and I bought a Golden Rod wireless digital hygrometer by Battenfeld/Lockdown. It had good reviews plus I liked the feature about being able to measure the temp and humidity from inside the safe on a display monitor on the outside of the safe. First I did a simple test. I took both hygrometers outside the safe and left them on my desk for 24 hours. The temps matched up, but the humidity percentage was way off. Then I placed them back into the safe and waited 48 hours. The temps matched up again, but the humidity was still way off. For example, the Caliber III reads a temp of 69 degrees in the safe with a humidity of 27%. The Golden Rod measured the same temp but with a humidity of 42%. </p><p><br /></p><p>Both meters say that they have been calibrated at the factory and that no further calibration is necessary.
