Features
| Definition of an Impedance Analyzer |  | Impedance analyzers perform sweep measurement to ascertain the characteristics of the object under measurement while continuously varying the measurement frequency and measurement voltage followed by equivalent circuit analysis to calculate the value of each component of which the object under measurement is comprised based on the frequency sweep measurement results.
*Impedance: A measurement of the difficulty with which current flows through an AC circuit, expressed in ohms (Ω). | |

| Product Features | | - Electrochemical equivalent circuit analysis functionality, enabling characteristics of materials and components to be evaluated
The IM3590 provides four equivalent circuit models for evaluating the characteristics of electrochemical materials and components. By using these four models to analyze measured values obtained by continuously varying the measurement frequency, it is possible to estimate parameter components such as charge transfer resistance and electric double layer capacitance.
- Measurement from the low frequency of 1 mHz
Impedance measurement of electrochemical materials and components in devices such as fuel cells needs to be performed at low frequencies, and the IM3590 can perform such measurement at a frequency of 1 mHz.
- Display of Cole-Cole plots
The IM3590 can also display a graph known as a Cole-Cole plot, a method for measuring impedance that provides a visual indicator of how characteristics vary with frequency.
- Support for 18 measurement parameters
The IM3590’s 18 measurement parameters, including the dielectric constant (ε) and conductivity (σ), are sure to meet operators’ measurement needs.
