Beginning to wonder if my hydrometer is faulty or not. Seems like it fluctuates between the 40's and 50's in humidity percentage every time I look at it, unless that's just from the CHE going on and off so the humidity rises and falls with it? Half of the water bowl is located under the bulb so that might also be why the readings are strange as the bulb slowly evaporates the water.

I do know the temperature readings on it are sound at least, matches my temp gun competently enough.
