SPECIFICATION

Order Code - 16958 Electronic Coulomb meter is suitable for charge measurement in the range of 10nC to 10mC. It uses a large 4½" x 2¼" rectangular meter for easy reading. For good many experiments it replaces conventional Ballistic Galvanometer. While using Ballistic Galvanometer, much of the time, care and thought of the students goes to it, so that the actual measurement becomes secondary.
To overcome this, an electronic device was developed which is mechanically steady and gives a steady deflection in an output meter proportional to the charge fed into it. The electronic device is essentially, an amplifier and an integrator followed by a buffer. The integrated charge get stored in a capacitor and the voltage across the capacitor is measured using a voltmeter through a unit gain amplifier (buffer).
