Is it a digital? Might not be a bad idea to salt test it again. Some hygrometers read low when the batteries get weak.

How is the seal of the humi? When you drop the lid down does it slam? Try the dollar bill test.

Where is the humi from if you don't mind me asking? I got a humi from ebay before that had a non-existent seal.
