D'Addario Humidity & Temperature Case Sensor

Monitor case conditions to help protect your instrument

Wood instruments are sensitive to dry heat, high humidity, and sudden temperature shifts—especially during winter heating, summer travel, or frequent moving between venues. The D'Addario Humidity & Temperature Sensor gives you an easy way to check relative humidity and temperature inside your case, helping you make informed decisions about humidification and storage before issues arise.

A clear digital display offers at-a-glance readings, while a programmable humidity set point lets you quickly see when conditions fall below your preferred minimum. The sensor also tracks recent high and low readings with date and time, so you can understand trends over days or weeks rather than relying on a single momentary check.

Features & Specifications

• Temperature Range: -35°C / -32°F to 50°C / 122°F
• Temperature Precision: Displays in °C or °F for quick comparisons during seasonal changes.
• Humidity Range: Low (under 20%) to 99% RH
• Humidity Accuracy: Approximately ±5% RH
• Min/Max Memory: Records high/low humidity and temperature with date/time.
• Programmable Set Point: Track your chosen minimum humidity level.

For best results, place the sensor where air circulates inside the case and pair it with a quality case humidifier when needed to keep conditions stable.
