Yes yes it is!!! Reading perfectly, infact I think the humidity is reading even more accurately.
But I also have a pic here of the hydrometer and how I mounted it inside teh thimble!!!! (Please don't worry about my crappy looking hot glue lol)
I am looking to get some bigger buttons to use instead of the thimble as it sticks out a good bit and will easily be taken down if he gets on top of it I am sure. But it SHOULD do for now until I get the buttons!!!

Also, you can see as I took each pic the humidity was rising lol, I had the tub open while installing the probes, so all the heat and humidity got out, thats why its going back up!!!!
