Got To Love My Hygrometers

I just tried the salt test for the first time, having previously used Boveda packs. Prior to the salt test, my hygros were reading around 65% (the normal RH for the beads I use). After the salt calibration, my 3 hygros all read 71%-72% in my cooler. I think it's the salt calibration, not higher relative humidity. And I was hoping I had found an almost free way to calibrate.

The thing with the salt test is that you need to use a specific amount of salt with a smaller (specific) amount of distilled water. If you have too much or too little water, or impurities in the water (tap water) then the RH will be off a little.

Boveda packs are easier...

Easier.. and that I was sure it was accurate. There was no worry.

The only one I've owned that doesn't seem to have any episodes is an Oregon Scientific. It's older and I got it Radio Shack. The closest current product I could find like it is here or here. It's not real clear from the web site whether these now require remote sensors but the first link looks almost exactly like the one I have (the logo is more current) and it has a built in sensor

I have two Oregon Scientific units myself and I love them. The also transmit to my base station so I can monitor them any time. They are great except for the cost...

I agree, its more accurate to just use a boveda calibration pack.


The only hydrometer I check once a week is the one in my desktop that has 60% beads. My vino I spray the inside of the glass every once in a while. It holds RH so well I dont need to worry about it.
