D'Addario Humidity And Temperature Sensor Bundle

D'Addario Humidity & Temperature Sensor Bundle (PW-GH-HTS)

Protect your instrument from the inside out. The D'Addario Humidity & Temperature Sensor Bundle pairs a guitar humidifier with a digital sensor so you always know exactly what conditions your instrument is being stored in — and can act before damage occurs.

• Includes the D'Addario Acoustic Guitar Humidifier and Humidity & Temperature Sensor
• Digital sensor monitors real-time humidity and temperature levels inside your case
• Alerts you when conditions fall outside the safe range for your instrument
• Humidifier releases moisture slowly to maintain optimal humidity (45–55% RH)
• Safe for acoustic guitars, classical guitars, and other wood instruments
• No batteries required for the humidifier; sensor uses a standard coin cell battery

Wood instruments are highly sensitive to humidity fluctuations — too dry and they crack, too wet and they swell. This bundle gives you the tools to monitor and control your storage environment with confidence.
