Meter – Dual Scale Voltmeter

Capacitance substitution box ideal for use in industrial and educational environments.
Unit will simulate capacitances from 100pF to 0.47F in steps ratio of 1:2

Used for measurement of small quantities of electrical charge.

Levelling 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 phosphor bronze alloy. Bakelite case, rigid and robust. Clamping arrangement for transportation. Consistent sensitivity over a large period. Strip provided for making it a periodic
