Electrometer

An Electrometer is a device used for the measurement of extremely small voltages,electric charges and currents. The voltage ranges begin at 0-2mV so that microvolts can be measured. The current ranges begin at 0-2 nanoamps and the electric charge ranges begin at 0-2 nanocoulombs. Output is provided for a logger or plotter.Instruments such as this are useful for measuring charge on Aepinus Capacitor plates or the electric charge around an electrostatic rod, or the current passing through an insulator or similar.
