HTS Humidity & Temperature Sensor.
The D'Addario Humidity & Temperature Sensor is a precision-engineered hygrometer that measures and displays humidity levels ranging from below 20% to 99%. Temperature is displayed in either Celsius or Fahrenheit, with a range from -35°C to 50°C (32°F to 122°F). The HTS features a programmable set point, and you can also store the date and time of the highest and lowest temperatures and humidity levels to which the instrument has been exposed. For optimal protection and control of your instrument, you should store this sensor along with one of D’Addario’s humidifiers and your guitar in a case.
