Hygrometer Calibration

[LazyLightning]

Hi folks,

As some of you know I just purchased 2 new humidors. I had been using a digital hygrometer in my older 100 count, but it was one that could not be calibrated. I was tired of making mental notes of how high or low the reading was off and decided to get a couple new hygrometers that can be calibrated.

I got 3 HygroSet Super Accurate Digital Hygrometers (the rectangle kind), and tried to calibrate them using the salt test first. After a week of trying and getting massive changes in Rh readings, I then used some of the Boveda calibration kits. I have to tell you these kits make it VERY hard to turn the calibration knob without opening the bag. To my mind it would be better to not open the calibration bag so that the Rh inside wouldn't change every time I made an adjustment. I also waited a full 48hrs before trying to calibrate them.

I have been calibrating them exactly how the paperwork says, and I am still getting reading that are between 4-7% off. I have also read that many others have the same problem with these units. So I am considering biting the bullet and getting a different kind of hygrometer altogether, as well as new calibration kits and start from scratch. Especially since I just started seasoning the new humidors, and have no way to tell whats going on.

These seem to get very good reviews and are also able to be calibrated, do any of you have any experience with them, or have any suggestions on something better. I will need 3 of what ever they are.

The one I am considering getting:

***EDIT-Well apparently these don't get the raving reviews I originally thought, so if you have better options I am all ears. I have been trying to get this sorted out for nearly 3 weeks now.

*Note, I know some of you will possibly be thinking just use the old one until you get this sorted out. I would but my wife thought I wanted her to throw it away, so I'm flying blind with my original humidor (320g 62% Boveda pack), my new foot locker (4-320g 65% Boveda packs) and the one I just started seasoning (4-320g 84% packs)

Thanks, any help would be VERY much appreciated.
