1 pack per 25 cigars in humidor would have been nice to know prior to ordering. i got 5 more on the 2 day mail. amazing, new humidor and bovida 84s are increasing the humidity. i was about to give up! thanks dave.
My first test with this we 3 Caliber IV digital hygrometers by Western Hygrometer. Convenient that all fit in at once. After 24 hours 2 read 75% and one read 72%. Instead of re-calibrating at that time, I let it go another day. After 48 hour, the 2 were still at 75% and the other had moved to 74%. At that point I assumed it was done and re-calibrated. Have since used on others. If you are looking for a simple solution and have 8 bucks to spare, this is it. Highly recommend.
Worked as expected.
Makes calibrating hygrometers such a simple process and if the bag is sealed it will be good for a while.
My pre-calibrated hygrometer read exactly 75% so the hygrometer and the calibration kit agree. It gives me a warm feeling that all is OK with both!
