This Digital Coulombmeter unit by Unilab is a quantitative alternative to the gold-leaf electroscope 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. A reset button discharges the unit as required. Two 4mm terminals on the top are used for connection to ground and to the charging body.
