Great I was just going to look into testing my cheapo ones and see how they were.

It needs more pictures!!! How about one of you putting water on the salt or soaking the water up with the paper towel. :p

I was going to test mine tonight so this helps save me time searching. Thanks for putting this up Rod.

Does it matter where you put it. I'm doing mine now an put it back in the humi. Is this bad?

Sorry for the delay, I just now saw this message now. Assuming your humidor is of the desktop persuasion, it's best to stick it to the underside of the lid. I always try to put the hygrometer somewhere in the middle of the humidor. Hope this helps...

I just got a ton of emails about this lately so I thought I'd share some info (in addition to the already great info supplied on the topic header) here:

Instructions for calibrating a XIKAR hygrometer with salt test:

Perfect timing as I just ordered one of these. It's also nice to see a manufacturer who has no qualms w/their hygro undergoing a salt test.

Here's my test today...
Just put in the bag...





4 hours of being in bag....




The black box is an eight cigar holder with built in hygrometer and such, from cigarsolutions I believe.

Kevin, that it a great idea. I'm yanking out all of my hygrometers and checking them together...including the travel humi's like you have there. Should have thought of that myself. :thumbs:

Leave them in the bag for 24 hours for a more accurate test.

Thanks Rod, just finished that, wife took off with the camera so here's the results written.

The travel hygrometer was most accurate at 76%

The white one was next at 72%

No. 1 black was 67%

No. 2 black was 69%

No. 3 black was 66%

No. 4 black was 71%

Now maybe I can get the clock'idor better regulated! Thanks for the tutorial!!!!!!!!!

Any questions just let me know. I've done it a few times. I followed the instructions here and it went great.

Thanks, Dave! I woke up this morning and was a little disappointed to see that it's only reading 46%. I put my hygrometer in the bag about 10 hrs. ago and at that time it was reading 39%. What does this tell me? Do I need a new hygrometer?

Is it digital?

If so, when were the batteries last changed?

How was the seal on the bag?

Yeah, it is digital. As far as the battery, I'm getting a new one today and then re-testing it.

On a different note, I tested that new Xikar I got at TTR yesterday, it's been in the bag (double lock Ziploc) for 12 hours and it's reading 54%. Should I adjust it from there, or leave it in longer?

Salt Test Calibration Instructions:
The rectangular digital hygrometer can be calibrated using the salt test calibration. To calibrate fill a plastic soda cap with plain table salt. Add just enough water to make the salt wet, but not so much that water stands on top of the salt. Place a zip lock bag flat on a flat surface. Place the salt filled cap inside the bag with the hygrometer. Seal the bag and wait 4 hours. After 4 hours have passed, push and hold the calibrate button until the hygrometer resets itself to 75%. Once the hygrometer has reset, remove it from the zip lock bag. The hygrometer is now calibrated!
