Humidistat
Continuously monitors relative humidity and detects if the ambient air is too dry or too humid.
A professional recommendation by Patrick Brennan, Piano Tuner.

After more than 25 years of experience in piano tuning and repair in Montreal and surrounding areas, I can state one thing plainly: humidity is the number one factor in a piano going out of tune and deteriorating.
That is why I recommend installing a Piano Life Saver, a humidity control system designed specifically for pianos by the Dampp-Chaser Corporation.
A piano is mostly made of wood, a living material that constantly reacts to ambient humidity. Without control, the consequences are inevitable:

Humidity control is smart prevention.
A well-protected piano ages better.
Basically, the Piano Life Saver system continuously monitors the humidity level inside your piano and automatically adjusts the air by dehumidifying or humidifying it, in order to maintain a stable and safe environment for the instrument.

Continuously monitors relative humidity and detects if the ambient air is too dry or too humid.
When the humidity level is too high, the dehumidifier gently warms the humid air to reduce excess moisture.
When the air lacks moisture, the humidifier adds the necessary amount of humidity.
Indicates that the system is on and functioning properly. Also signals when to add water or replace pads.
Contrary to popular belief, it is not the temperature that impacts your piano, but the humidity.
When the soundboard absorbs moisture, it swells and exerts increased pressure on the strings.
Result: the piano's pitch goes too sharp, especially in the mid and high registers.
When the soundboard shrinks, the pressure on the strings decreases.
Result: the piano's pitch goes too flat and becomes unstable.
The Piano Life Saver maintains constant humidity inside the piano, which significantly slows down pitch variations between tunings.

Protects your piano.
Preserves its value.
Whether you own an upright or grand piano, humidity control is an essential preservation measure.
My role, as a piano tuner, is also to guide you towards solutions that preserve your instrument and prevent costly repairs.
