Temp gun equivalent for humidity?

I have a temperature gun that I got from Pro Exotics, it's wonderful. My question is, is there an equivalent thing for measuring humidity? When you have multiple animals, buying a digital humidity gauge for each enclosure can get expensive.

There are - used mostly in flooring industry - but you'd be looking at a price tag in excess of $500.

If there are cheaper ones I wish I knew where to get a hold of them.

Oh wow, well that's too bad..

yeah that just a tiny bit out of my price range

I don't think there is really a cheaper one. A temp gun works on by measureing heat radiance (I'm not an ME, so I could be misquoting my friend). As for humidity there isn't really any sort of property that does that. I think a humidity sensor that would be really able to read something like that would be quite expensive..driving up the cost for the device.

The price we pay for instant gratification :sigh:

I'll have to remain content shuffling around the few AccuRites
