Perhaps the least recognizable of the instruments is the hygrometer. This device has been used for over two centuries to measure humidity, which helps predict fog conditions for navigational purposes. Finally, the thermometer uses a a bimetallic strip to measure temperature – another important factor for estimating weather. As you’ve probably noticed by now, all of these instruments are of course analog, not digital.
Prices are $5,200 for the barometer, $5,100 for the clock, and $4,400 for the hygrometer and thermometer. For more information, visit Panerai online.
