D'Addario Hygrometer Humidity & Temperature Sensor

The D'Addario Humidity & Temperature Sensor takes the guesswork out of protecting your instruments from humidity damage. It digitally displays relative humidity from under 20% to 99% and temperature in both Fahrenheit and Celsius, with a programmable set point to alert you when levels fall outside your target range. A built-in memory feature logs the peak high and low temperature and humidity readings your instrument has been exposed to, giving you a complete picture of its environment over time.
