Function and Applications

Operational amplifier with high resistance input for
quasi-static voltage measurement respectively charge measurement in
fail-safe-plastic housing.

Benefits


Suited for experiments with electrostatics e.g. charge
measurement, capacity measurement of sphere-capacitor, measurement
of direct voltages, quasistatic measurements and measurement of
small currents.
