Hi all

Recently I realized that my hygrometer in my pythons cage was a little off. So I bought another. I also have a digital one but its too big for the enclosure.

I tested to see which one is not working properly by placing them beside each other next to where the house thermostat is, watching the difference in humidity readings and comparing them to the house hygrometer. Whichever was not in line with the others is the faulty one right?

I was stunned to find that all of my hygrometers ( 4 in total) are giving me widly different readings. The house thermostat (also digital) says 40%, the digital one says 30%, one dial hygrometer says 20% and 2 other dial hygrometers say 55-60%!

The dial hygrometers are from exoterra and I'm not sure if they can be trusted.

How can all my hygrometers and my house thermostat be giving me seperate readings? Is there something about humidity physics I'm not aware of here or are all my meters busted?

(before you ask, my house thermostat's probe is where I tested all the equipment to make sure the playing field was even)

thanks all!
