I am new to the forums and look forward to visiting often. I found the setting up a humidor guide an awesome tool!

My question involves hygrometers. I just got my first humidor a couple weeks ago. A Thompson 200 count humidor with a Thompson digital guage. I followed all the steps provided by Thompsons, as I didn't know about this site. My humidor registers about 74% at 73-75 degrees (I'm in South Florida too).

I decided to get a smaller travel humidor and just got another Thompson travel that came with a analog hygrometer. I followed their instructions on placing the guage in a damp towel, which I did. The guage was near 95%, so I adjusted the screw sligthly to compensate and I placed the guage in my big humidor to see if it was close to my Thompson digital.

What I have found with that, is that it doesn't really change... It stayed at 95%, so a local shop said it probably wasn't working and I picked one up from them for $8. That one seems to work, but it never leaves the area of 70-75%, which I guess is ok, but I even took it out for a day and it never changed. Not sure what my humidity is inside the home with A/C on....

So I decided to buy a small digital one for the travel humidor. Guy at the shop said not to worry about calibrating it, so I just put it in the big humidor with my Thompson digital. The brand on the small digital guage is "Reindeer."

I found that the temperature reading is almost exact. Even to the decimal point, however the humidity was about 5-6% difference. The Reindeer reading higher. This even occurs wherever I put the two digital guages, outside on table, both in travel humidor or both in big humidor.

I guess I'm kind of a perfectionist, trying to find out which guage is accurate. Especially since they are off about 5-6%. So I found cigarsmokers forums and I am currently doing the salt test as recommended by the website post. I've had my cap of salt in a sealed baggie, inside a second one. I used distilled water and added about 4 drops of water to the salt. I put both digital guages inside and in a dark room.

After about 30 minutes, the Thompson reads 90% and the Reindeer reads 99%. I know from reading that it needs time to stabilize in the baggie. So I will leave it in there for the prescribed amount of time.

My question is.... Should I be overly concerned with two digital guages being that much off? I assume there is not a way to adjust them and I figure whichever one is closet to 75% after the salt in bag test, will be the most accurate.

Thanks.
