COULOMBMETER DIGITAL

This unit provides a way to investigate electrostatics quantitatively. It acts as a digital electroscope measuring positive and negative charge on the digital LCD display. It can be charged by contact or by induction by bringing a charged body up to the 25mm collecting plate. A reset button discharges the unit as required.

With internal capacitance 1µF, and max. p.d. between terminals of 100V. It can be charged by contact or by induction by bringing a charged body up to the 25mm collecting plate. The 3½ digit display shows charge in the range of -1999 to +1999nC.  Two 4mm terminals on the top are used for connection to ground and to the charging body.
