Ultra-precision

Capacitance Bridge

The World’s Most Accurate 50Hz-20kHz Capacitance/Loss¹ Bridge

The AH 2700A offers unparalleled stability, resolution, linearity and accuracy in a multi-frequency capacitance/loss¹ bridge (whether manual or automatic). Its numerous state-of-the-art features make it an exceptionally user-friendly instrument. The precision of the AH 2700A is creating new applications in calibration, science, and production in a wide range of fields.

Frequencies: 50, 60, 80, 100, 120, 160, 200, 240, 320, 400, 500, 600, 800 Hz and 1.0, 1.2, 1.6, 2.0, 2.4, 3.2, 4.0, 5.0, 6.0, 8.0, 10, 12, 16 and 20 kHz

[1] The term “loss” is used to refer to the component of the impedance which is 90° out of phase with respect to the capacitive component. The AH 2700A can report loss in units of conductance, dissipation factor, series or parallel resistance, or loss vector.
