What brand of Hygrometer is accurate?

[Holly31]

I'm having an awful time finding a hygrometer under $50 that is rated by users as accurate. How accurate should it be? Within 5-10% ? I'm in the desert and our humidity usually runs about 5-8% outdoors, 25% indoors, so this is a concern for my next hatch as the last one was not successful.
I'm using a Brinsea probe thermometer in a Little Giant 'bator with fan and turner.

Hmmmm....could you add a wick to the probe thermometer and get your humidity that way?

I'm a little confused on the wick vs the normal dial type method. I hear something is 60%, then wet it is 85%, and not sure if I'm doing what I"m doing right in the first place.

I tried to follow the bator directions, but I'm pretty sure I overwatered, because we're pretty dry I never let the water get low and had a large surface area in the pan, although never to the foggy-window point.

I was wondering if the cigar humidor hygrometers are accuarte enough, or the reptile terrarium brands are good. I've heard Flukers are not accurate, then I've hear of adjustable models - how the heck can I adjust it when I am the one who needs to know what it is?

If anyone has a good one they can recommend I'd be grateful!

You could try something that Tuffoldhen suggested to me. I am just using two different brands of hygrometers (both ran between $7 & $8 each). If one reads 52% and the other reads 48% than I am just going to go with a reading right in between the two. I would go with 50%. Hope that helps you out! It sure beats paying a ton for one!

Ah, for this there is the "salt test".
If you do a search I think you will find references to how to do it.
It will tell you if your hygometer is accurate and/or by exactly how many percentage points it is off.
