Jahn Hygrometer

The hygrometer measures the humidity around the piano and helps you maintain the optimal conditions for your instrument. Changes in humidity are the biggest culprit when it comes to a piano sounding out of tune. With a hygrometer, you can measure the relative humidity yourself. For the piano, the more stable the environment, the better. A piano in a room with a constant climate will stay in tune longer than one placed, for example, in a drafty room near the door.
