This is a second unit for me. This one does not agree with multiple other hygrometers I have. I did the salt test and it came out higher than it should have. I suspect the calibration certificate I have is not worth the paper it is written on. I am not convinced that you can trust the promise of calibration for this unit.

We had this for less than 2 months. The readings were incorrect by at least 15%.

We have used these for years where I work and now I have two at home. They come with a calibration certificate. Side by side, after a reasonable time, the readings always show good correspondence. They are attractive, reliable, and easy to set.
