Protect your guitars from cracks or swelling! Monitor humidity and temperature to help protect wood and finished instruments. Excess dryness makes wood shrink and crack. Excess humidity swells wood and blushes newly sprayed finishes. Our large, easy to read gauge monitors Fahrenheit/Celsius temperature and relative humidity in workshops, wood storage areas, guitar display cabinets and finishing rooms.
