Cigar Q&A: Hygrometer Accuracy

Cigar Q&A: Hygrometer Accuracy

Do You Have Hygrometer Accuracy Woes?

Q.I have a 100 count humidor with two humidifiers. I’ve done the salt test on my hygrometer and 60% is 75%. I’m only using one humidifier now and I’m showing 67% RH which relates to about 82% if i can believe the salt test. What do you think: new hygrometer?
– Fred B. in Texas

A. My philosophy is that if you know the actual RH by “doing the math,” then I see no reason to invest in a new unit, assuming it’s analog and you want to go digital. I have a digital unit that’s off by 10 points. So if it reads 60%, I know it’s reallly 70%.

If your hygrometer is analog and you can calibrate it, when you’re done with the salt test, depending on where the needle is, move it to 75%. It takes about 6 hours to do the test right. You may find it a little more accurate. In other words, you won’t have as wide a gap when you read it.

Some manufacturers now make a digital hygrometer that you can calibrate, so you might want to look into one of those.
