Humistat Model 3 Humidifier
The Humistat Model 3 instrument humidifier is an adjustable, case‑mounted system designed to maintain proper moisture around larger instruments. Its durable, clear polycarbonate body holds water and releases humidity—not liquid—so it helps reduce cracking, warping, and shrinkage caused by dry air. The regulator sleeve allows you to control moisture output, and the unit fits securely inside most instrument cases without sponges, gels, or refills to purchase.
Key Specifications:
- Diameter: approx. 2 5/8″ × height: 3/4″
- Case‑mounted humidifier for larger instruments
- Adjustable control sleeve for variable moisture release
- Clear polycarbonate construction lets you see water level
- No sponges, gels, crystals, or refills required
- Suitable for cellos, basses, guitars, bassoons, and similar sized instruments
