The D'Addario temperature/humidity sensor is a precision digital hygrometer that indicates relative humidity from low values (below 20%) up to 99%. Temperature is displayed in degrees centigrade or farenheit, from -35 to 50°C (-32 to 122°F). The HTS sensor includes a programmable threshold and memory function indicating the time and date of the highest and lowest temperature/humidity readings to which the instrument has been exposed. Get one for each of your instruments. Installing and using an HTS sensor and a D'Addario humidifier in each of your cases is a wise investment you won't regret.
