It fulfills most low-voltage parameter measurement needs for components and materials with its basic accuracy (0.1%), wide frequency range(from 20Hz to 5MHz). The instrument is widely applied in microphone, resonator, inductor, ceramic capacitor, LCD, varactor and transformer .etc to analyze electrical performance and test low-ESR capacitor and high-Q inductor. With the super high test speed, TH2826 series is especially for frequency response curve analyzing of detector and piezoelectric device on auto production line. Its multiple output impedance mode can be used for different standards of inductor or transformer manufacturers. With its prominent performance, TH2826 series is in conformity with commercial and military standards, such as IEC and MIL standards.
