LCR meters, impedance analyzers, and capacitance meters are all electronic test instruments used for measuring the properties of components, but they differ in their scope and complexity. A capacitance meter is the most specialized, designed to measure only capacitance, while an LCR meter measures inductance (L), capacitance (C), and resistance (R) at fixed or limited frequencies. An impedance analyzer is the most versatile, as it measures complex impedance across a broad, continuous range of frequencies and displays the results graphically, making it suitable for detailed analysis and advanced characterisation of components and materials.
