The humidity management system comes with a beautiful brass hygrometer that provides the humidity reading at all times. You can monitor the humidity level and action appropriately before atmospheric elements do any damage to the violin. With the humidifier, you can increase moisture in the case to the appropriate level. This is especially useful during the winter time when the air is dry. Since this humidifier is attached to the case, water would never come in direct contact with the violin making it a much better choice than the humidifiers that get inserted into the violin directly.
