Description

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.

Key Features

Electrometer gain factor: 1.00

Input resistance: >1012 ?

Output resistance: <1 k?

Input current: <10 pA

Input capacitance: <50 pF
