My dad gave me this wee barometer/altimeter, made about 1890. Took it out in the Mull hills yesterday - it's as accurate, and smaller, than mobile phone GPS π€© π₯° . The longevity and reliability of this 130-year old technology seems inconcievable today. And no spurious precision! π€ #InstrumentationDoneRight #Altimeter #Barometer #Mull #Antique
