Ballistic Galvanometers, 100 Ohms

Product Code: 1146201

Used for measurement of small quantities of electrical charge and currents. Leveling Screws for balancing the coil. Coil with mirror suspended between long suspension at the upper end and a spring at lower end. Suspension and spring are made of special alloy to provide high degree of sensitivity to the movement. Movement housed in a Bakelite case, rigid and robust. Clamping arrangement for transportation. Consistent sensitivity over a longer period. Strip provided for damping its ballistic movement.
