Caliber IV Digital Hygrometer by Western Humidor (Oasis)
Industry Standard. Caliber IV is the most accurate humidity / temperature monitor that could be easily placed in your room or guitar cases.
The most accurate humidity/temperature monitor
Experienced luthiers always maintain 40-50 percent relative humidity in their shops, the range at which wooden stringed instruments are most stable.
Excess dryness causes wood to shrink, lowering the action, which may cause buzzing of the strings against the frets and cracks in the wood itself may appear.
Too much moisture can cause wood to swell which raises the action and newly-sprayed finishes to blush.
Make sure you get an accurate hygrometer,
and keep your precious guitar in the right humidity all the time!
