About 3B Scientific U8531408-115 Electrometer, 115V
Experiment topics: Measurement of charge and voltage in electrostatics, Measurement of charge and voltage for a plate capacitor, Ionisation of air by burning gases or a radiation, Hallwachs effect (external photoelectric effect). Impedance converter with high-resistance input for measuring extremely small charges and currents. The input signal is converted into a proportional voltage, which can then be measured with an external voltmeter. During the measurement the potentials of the electrometer and the experimenter must be matched by using a metal rod connected to earth. Includes a 12-V AC plug-in power supply. Electrometer gain factor: 100. Input resistance: less than 1012 ohms. Output resistance: greater than 1 kiloohm. Input current: greater than 10 picoampere. Input capacitance: greater than 50 picofarad. Max. output voltage: +/- 8 Volts. Resistance to excess voltage: 1 kilovolt (from low-resistance sources). 10 kilovolt (from high-resistance sources). Supply voltage: 12 VAC. Dimensions: 110 x 170 x 30 cubic meters approximate. Weight: 1 kilograms approximate.
