Hygrometer - Brass - Schmidt Amsterdam

Vintage precision hygrometer housed in a solid brass case, with a clear 0–100% relative humidity scale.

The reverse still retains the original Schmidt, Amsterdam – Rokin 72 retailer label, adding an attractive Dutch provenance. The casing has ventilation openings for the hygrometer mechanism and a sturdy suspension ring.

The instrument has been tested and functions well. The brass shows normal signs of age and use, including light scratches and natural patina, all consistent with its vintage character and visible in the photographs.
