- Protect your instruments from humidity and temperature issues: monitor humidity from 20 to 100% RH and temperature from -25 to 55 C (-13 to 13 F) to help prevent wood cracking, warping, and finish problems. The device provides a clear readout to support proper climate control for guitars, violins, and other string instruments. - Easy to read, with switchable display: the thermometer hygrometer shows temperature in either Celsius or Fahrenheit, making it simple to use in any region or setup. - Built for quality and style: round, compact design with an alloy frame that offers exquisite workmanship and an elegant appearance. Durable construction helps it hold up in instrument cases and studios. - Portable and space-saving: round and lightweight, it occupies minimal space in cases, on shelves, or in compact work areas. Its compact form does not intrude into instrument storage or performance space. - Practical applications and use scenarios: - In instrument cases during travel or long-term storage, to ensure the internal environment stays within safe humidity and temperature levels for wood instruments. - In studios, rehearsal rooms, or music shops where multiple instruments are stored, to continuously monitor environmental conditions and protect valuable assets. - In home or workshop settings where guitars, violins, or other wooden instruments are used or kept, helping maintain optimal ambient conditions for performance and longevity.
