c. 1900 - 1920

A small metal device with frayed, black elastic wrist band used for the graphic recording of the pulse, the forerunner to the modern electrocardiogram. The instrument is engraved 'Krohne & Sesemann, London'. The device was strapped to the wrist so the pulse could be transmitted to a lever and recorded onto smoked paper. It was manufactured prior to 1900 and owned and used by Dr Alfred Webster at Perth Public Hospital.
