Andeen-Hagerling - Model AH 2500A -1 kHz AutomaticCapacitive Bridge
Andeen-Hagerling's Model 2500A sets a high benchmark in capacitance and loss measurement with its precision and versatility, designed with a unique ratio transformer and a temperature-controlled fused silica standard for exceptional accuracy. Operating at one kilohertz, the Model 2500A allows measurements independent of test frequency, catering to medium and high-impedance ranges. It includes various interfaces like RS-232 and IEEE-488, supporting automated, user-friendly operations with English language commands. Notably, it features calibration functions against both internal and external standards, incorporating a passcode system for security. The Model 2500A can process DC Bias and corrects for cable length impacts on measurement accuracy. With a robust build adhering to UL, IEC, and FCC standards, coupled with a three-year warranty, it is well-equipped for rigorous industrial and laboratory use. Its capability extends beyond calibration, exploring applications in various fields requiring precision capacitive sensor integration.
The AH 2500A offers unparalleled stability, resolution and accuracy in a capacitance/loss1 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.
