Barometer - Wm. Widdop Triple Baro Thermo Hygro
Triple consists of a barometer, thermometer and hygrometer that are attached to a highly polished piece of wood with brass fittings and finely shaped hands and dials. The Barometer has two hands, apart from the hand that displays the current air pressure there is another manual hand that you can set milestones with and thus also makes it possible to follow the change in pressure (you can set a point of reference with the manual extra hand). The hygrometer, which measures humidity, can be calibrated manually for increased precision and the thermometer shows the temperature in both Fahrenheit and Celsius.
