Calibration of a Hygrometer...would this work

I understood the OP's question to be about using the packet you describe in item 1. I probably should have been more clear about that in my earlier answer.

I agree, the Fuente packs would probably only be good for traveldors.

The Fuente packs that I have are mostly 69RH, but I have one that is a 65 and thought I had another one around here with a third value on it, but I can't find it. It's either lost or maybe I gave it away. The RH levels are printed on the pack by a separate machine, they aren't part of the regular printing and the fonts aren't the same between the various packs. It includes some other info, possibly a lot/batch number. Now, it's possible that things have changed as these packs are old, I've had most of them since 2005 I think, and just keep recharging them. Just for grins, I threw one in a bag with a hygrometer to see what it does. Doesn't seem to be doing much. Maybe I should actually put a battery in my hygrometer first before trying this.

So, from what you're saying, it looks like the hygrometer kit is the same technology, just a more accurate pack. Thanks for the clarification.

No worries - hydrometer, hygrometer what's the difference anyway.

I actually thought he could have been referring to the larger or smaller packets, I usually have both lying around if I have been ordering singles.

Honestly, I think the bigger packets are probably pretty accurate as well, but I could be wrong.

They have a humidity range on the packets, I believe the 65% packet says 61-65% (I just bought some this past weekend as I still use them in my desktop humidor that only has two cigars in it ). I assume they do this to prevent getting complaints that the packets aren't working correctly.

I figure most people need to raise the humidity in their humidors not lower it and you obviously lose humidity when you go in and out, so I think the range makes a lot of sense for them.

I decided to set up an experiment as well. I placed two hygrometers in a plastic container with a really good seal with a brand new 65% packet. I will check it this evening and tomorrow after 24 hours.

It is not a perfect experiment as it is a little warm today and the hygrometers I am using have not been calibrated in 2-3 years (they are within range for my cabinet).

I really do not worry about humidity that much these days as my cabinet is only 15% higher than my house most days.
