One of the first accurate measurements was with the oil drop experiment. http://en.wikipedia.org/wiki/Oil_drop_experiment

You can also study a related measure, the charge-to-mass ratio in a cloud chamber with a superimposed magnetic field. http://en.wikipedia.org/wiki/Cloud_chamber

These will only give you multiples of the electron & proton charge, despite many attempts to measure fractional charge. It is thought that quarks carry fractional charges, but they are never found in isolation at energies that we can achieve.
