Coulomb Meter -1999 to 1999 nC Digital Electroscope Plant cell model 16cm Giant Large Sand TimerThe Coulomb Meter provides a means of exploring and understanding static electricity and charge. Digital Coulomb meter for use in electrostatics Provides a quantification of electrostatic charge strength in a plus minus range of 1999 nC with an accuracy of 10 nC. Display shows the number of Coulombs deposited into the instrument by current through a resistance, from a capacitor, or from a source of static electricity 100V maximum. A useful tool in
