Customer Reviews

Actually works
I had four small hygrometers that gave four different readings, so I tried this kit. Now they give me the identical readings.

Great product
This is the perfect tool if your looking for a cheap way to calibrate your digital hygrometer. Make sure you let your hygrometer sit in the kit for 24-36 hours.

Worked great and I would definitely recommend it! 5*

Cal Kit
This was well worth getting at the same time as the digital hygrometer. The instructions were good and it was easy to calibrate my hygrometer.
