AH2550A single frequency capacitor bridge

AH2550A measures capacitance and losses in the medium to high impedance range, allowing for the use of 3 terminals instead of 5 to connect the tested device. Its unparalleled precision lies in the design and production of a 40 year capacitor bridge. That is, the result of uniquely designed transformer ratios. Equally important, the unique temperature control and standard fused silicon capacitors give it high measurement stability and immunity to mechanical shocks. These elements form a true 1kHz independent and precise test capacitance loss

The capacitive bridge that consumes the result.
