Andeen Hagerling 2500A 1khz Automatic Capacitance Bridge

Automatic Capacitance Bridge


The AH 2500A offers unparalleled stability, resolution and accuracy in a capacitance/loss bridge (whether manual or automatic). Its numerous state of the art features make it an exceptionally user friendly instrument. The precision and ease of use of the 2500A are creating new applications in science, engineering and production in a range of industries.


• Accuracy of 5 ppm (or 3 ppm with Option E)

• Stability better than 1 ppm/year (or 0.5 ppm/year with Option E)

• Resolution of 0.5 attofarad (.000 0005 pF) and 0.15 ppm (or 0.5 aF and 0.07 ppm with Option E)

• Temperature Coefficient of 0.03 ppm/°C (0.01 ppm/°C with Option E)

• Measures extremely low loss down to a dissipation factor of 1.5x10-8 tan delta, a conductance of 3x10-7 nanosiemens or a resistance up to 1.7x106 gigohms

• Full precision measurements in less than 0.5 second and repeated measurements on the same sample in less than 40 milliseconds

• Both capacitance and loss ranges cover negative values to allow for unusual samples or three terminal networks

• Three terminal BNC connections minimize connector costs and number of cables

• Commutation (test signal reversal) to minimize external power line or other periodic signal pickup

• Autoranging
