DEHUMIDIFIER DAMPP-CHASER PIANO LIFE SAVER SYS. MOD. H-D, PN: 72596, NEW IN BOX

HOW IT WORKS: 
At its most elemental, the Piano Life Saver continuously monitors the humidity inside your piano and gently dries and humidifies to maintain a stable environment.  
The HUMIDISTAT constantly monitors Relative Humidity and senses whether the surrounding air is too dry or too damp.
The DEHUMIDIFIER:  When the humidity level is too high, the dehumidifier kicks in and warms the damp air to encourage proper air flow and lower moisture levels.
The HUMIDIFIER:  When there is not adequate moisture, the humidifier kicks in to supply moisture.
