EARLY VOLTMETER, MFD. BY JULES ADRIEN MARIE LOUIS CARPENTIER (1851-1921) INPARIS. VOLTMETER DESIGN PATENTED BY CARPENTIER & MARCEL DUPREZ (1843-1918), A FRENCH ELECTRICAL ENGINEER. DEPREZ INVENTED THE 'FISHBONE GALVANOMETER', A POLARIZED IRON INSTRUMENT WHOSE COMBINATION OF LIGHT MOVING PARTS AND STRONG MAGNETIC FORCES (EXERTED BY A POWERFUL PERMANENT MAGNET MOUNTED NEARBY) ALLOWS THIS LOW-SENSITIVITY INSTRUMENT TO RESPOND VERY RAPIDLY TO CHANGES IN CURRENT. THESE INSTRUMENTS CAN BE USED TO MEASURE BOTH DIRECT & ALTERNATING CURRENTS. (REF.1,P.18). GIVEN THAT VOLTMETERS WERE UNKNOWN BEFORE C.1879, THIS CARPENTIER EXAMPLE REPRESENTS VERY EARLY VOLTMETER. - Area Notes
