heartfelt beads and hygrometer calibration

[timatraw]

Im having a heck of a time getting an accurate calibration reading for my stinking hygrometers. Is it possible to use a cap full of 65% beads (half wet with distilled water) in a tupperware with the hygrometers and get an accurate reading? I am guessing that the RH should be 65% after 24 hours or so.
Will this work?
Has anyone tried this calibration method with success?
Thanks.

The beads can emit or absorb humidity based on conditions, so I would do the salt test rather than a test with beads for a more accurate reading. :2

if you really want the easiest method get yourself some Boveda Calibration Kits. Not as cheap as salt, but they are only $3.00 and you dont have to fuss with anything.

I have used this method and agree it is easy and accurate. :tu

That is the answer in my book as well:D

I did the Boveda Calibration Kit it was easier than doing any kind guessing. Well worth the 3 bones, clams or whatever you call them.

I agree, the calibration kits are the easiest way to do it. You cant mess up.

The salt calibration is far from difficult. In fact, you can easily be done days before your paid-for kit arrives in the mail. :2

:tpd: Really easy!

Haven't tried it myself but it should work fine, as will any of the methods given. I might suggest you use a clear zip-lock bag. You can see the reading without opening the container.

Well, the salt test is actually a calibration method that relies on some fundamental science. Its like using boiling and freezing water to calibrate a thermometer. The temperatures are known constants.

If you calibrate using the beads, than your hygrometer is basically calibrated using the same thing you're measuring. Its not independent.

Excellent point sir :tu

I have been using the salt test on mine and have had no problems

:tu I Used The Regular Table Salt & Never Got An Accurate Reading. Go With The Boveda Kit!:2:tu

The salt test is one of those internet cigar mysteries. Some folks find it easy, others don't. So, there's nothing wrong with buying a Boveda pack. According to their website, its really the salt test. So, I guess you are paying for a premixed slurry. OK with me!

Salt test is pretty easy, just think paste instead of soup and you're pretty much on the right track.
