TFA Thermo-Hygrometer

You can better care your instrument

Well-made, lightweight and accurate (its reading is consistent with my other hygrometer, which I know and trust).
The dial is in black and white only, which I personally find cleaner and more easily legible; the ideal humidity range is designated in bold letters.
All in all a great choice, it eliminates any guesswork when trying to properly humidify your guitars or similar instruments.

Wonderful product, happy to have it! :)

Finaly found a hair hygrometer which can be ajusted and calibrated with the 'salt test' This is NOT junk like all the others one finds on aliexpress etc

I have one in my room for my double bass. Helps me keep an eye on humidity so no cracks appear. Also gives temperature so helpful in keeping the house cool during the hot seasons :)

Perfect, no battery and easy to read.
