Excellent hygrometer. Precise, easy to read and incorporates temperature as well.

terrible digital

Tried numerous times to read and understand the directions. Finally gave up and was unable to attempt to calibrate it. Maybe there's a nuclear scientist out there that could decipher the instructions. Very disappointed.
