Maple Digital Barometer

Description

The boiling point of water is often stated to be 212°F, though this is only true at 1 atmosphere of pressure, commonly referred to as sea level. Without weather, atmospheric pressure decreases as elevation increases. But we live in a world with weather, which means atmospheric pressure (even at sea level) changes throughout the day. For example, water will boil at 209.6°F with a pressure of 28.5 inHg. When the pressure rises to 29.25 inHg the boiling point increases to 210.9°F, a difference of 1.3°F. 1.3°F is the difference between 63.6% and 66.9% syrup.

This device measures barometric pressure every two seconds to determine the boiling point of water, no matter the elevation or the weather. Simply connect the included USB C cable a power source (e.g. a phone charger, portable battery pack, or computer). The unit will automatically turn on and display the current barometric pressure (in inches of mercury, or inHg), the boiling point of water in Fahrenheit, and the boiling point of syrup at a density of 66.9%. You can adjust the unit to display the temperature to get syrup to any density from 62% to 68%.

These devices were designed and assembled in Plymouth, Connecticut. If you would like your device customized (e.g. to display in Celsius or a different Brix range, just let me know). Includes the digital barometer, a USB C power cable, and operating instructions.
