Hydrometer

This is a great little hydrometer. It's stayed in place since the day I placed with. Much better than one with a stand or double sided sticker.

Omg I am in love with this!!! I have tried so many and they just don't stay up - biggest peeve, but this magnet system rocks!!!

The magnetic hygrometers are a must have! They are perfect for enclosures and are nice and secure.
