1621 Capacitance Bridge.
1621 Capacitance Bridge represents the first major improvement in nearly a decade in ultra-precise laboratory capacitance intercomparisons and dielectric measurements.
Three integrated units: precision ratio-arm bridge, highly stable oscillator, and an extremely sensitive detector.
Completely self-contained system Capable of capacitance measurements in increments as small as 0.1 µF (10-7 pF) and conductance measurements in increments as small as 100 aS (10-10 µS; equivalent to a shunt resistance of 1010 MΩ)

1621 Capacitance Bridge.

Model  Description 
1621  1621 Capacitance Bridge.

Range 10-7 pF to 10 µF, 12-digit readout.
10-ppm basic accuracy.
frequency range 10 Hz - 100 kHz.
Measurements are three terminal, with 2- or 3 terminal connection, and provision is also made for the connection of an external standard for comparison measurements.
Little degradation of performance occurs from 10 Hz to 10 kHz and operation to 100 kHz is possible.
Balances are achieved by in-line readout lever switches-easily adjusted and read correctly.
All digits of capacitance and conductance, as well as pertinent multipliers, are also provided by BCD-coded contact closures, available at rear-panel connectors for use by printers or data-processing equipment

Most of the bridge's internal standards are enclosed in an insulated housing to reduce the effects of ambient temperature changes; unused standards are disconnected to reduce shunt capacitance at
the detector input.
Oscillator provides up to 125 V or 5 A for sufficient signal to be detected even with unbalances as small as one part in 108 of 10 pF.
Detector contains three meters to help you speed the balance: One displays the magnitude and the other two simultaneously display the in-phase and quadrature components of any unbalance.
