New here! Hygrometer calibration question
Posted: Thu May 21, 2020 8:51 am
Hi, we are brand new here! And pretty new at hermit crab stewardship too, but trying really hard to get everything right. This is our first post.
We have two analog hygrometers in the tank currently but they vary widely on their measurements. For instance right now one says 82% and one says 85%, but last night they were further apart. I think one may just be more sensitive than the other.
I am adding a digital Acurite thermometer/hygrometer to our setup, to try to get a more precise reading. Last night I put it in a sealed food storage container with a shot glass half-full of wet salt. But this morning it was only at 65% after about twelve hours. So I've moved it to a ziplock bag instead; the percentage dipped down into the 50s and is now climbing back into the 60s again. I'll leave it all day to see what happens.
So my question is - what percentage do your own digital hygrometers deviate? Is this salt test really reliable? And how much difference do you all regularly take into account, before you just throw up your hands and try something else?
