ELECTROMETER and COULOMBMETER.
ELECTROMETER / COULOMBMETER This equipment enables the determination of electrostatic load. It is composed by condensers with fixed capacity that are charged from electrostatic charges. A voltmeter measures the voltage condenser and it enables to determine the charge accumulated. CHARACTERISTICS: • Range: +/- 150 nC Input impendence: >= 1013 ohm Amplifier input capacity: 0,01 μF; 100 nF
