PART OF LARGE & VARIED COLLECTION OF OVER 7500 ELECTRICAL ITEMS ACQUIRED & DOCUMENTED BY ONTARIO HYDRO IN 1960S. COLLECTION WAS THOUGHT TO BE LARGEST & MOST COMPREHENSIVE IN CANADA & WAS DONATED TO NMST IN 1992.
Function
INSTRUMENT FOR DETECTING EXISTENCE & DETERMINING STRENGTH OF SMALL ELECTRIC CURRENTS.
Technical
REFLECTING OR MIRROR GALVANOMETERS USE BEAM OF LIGHT REFLECTED OFF MIRROR & ON TO SCALE TO PRODUCE READINGS, IN ORDER TO MINIMIZE EFFECTS OF EARTH'S MAGNETIC FIELD. WALL GALVANOMETERS WERE MOUNTED ON SOLID WALL TO PREVENT VIBRATION, & TELESCOPE & CURVED SCALE USED TODETERMINE DEFLECTION OF GALVANOMETER (REFS. 2&3).
