Campbell-Stokes Sunshine Recorder – Optical Glass Sphere Meteorological Instrument with Wooden Box

This Campbell-Stokes sunshine recorder is a genuine meteorological instrument that concentrates sunlight through a precision glass sphere onto a recording card, leaving a burn trace whose length reveals how many hours of sunshine a location received that day. The roughly 10cm glass sphere sits within an adjustable frame on an equatorial mount with adjustable feet and a bubble level, so it can be aligned with the Earth’s axis and positioned near a sunlit window for accurate readings. Complete with a full year’s supply of chart strips and a wooden storage box, it’s ready for immediate use by weather enthusiasts, educators, and science collectors alike. Carefully packed in corrugated export packaging, this vintage-style instrument brings a piece of real meteorological history into a classroom, study, or science collection.
