LCR Meters

GAO’s electrical LCR meters are electronic devices used to measure the inductance (L), capacitance (C), and resistance (R) of electronic components such as capacitors, inductors, and resistors. GAO electrical LCR meters work by applying an AC voltage or current to the component being measured and then measuring the resulting current or voltage. The instrument then uses this information to calculate the component’s LCR values. Our electrical LCR meters typically have a variety of measurement modes and ranges, allowing them to measure a wide range of components accurately.


GAO’s electrical LCR meters are composed of source, signal conditioning circuitry, measurement circuitry, display, input and output connectors, control circuitry, and power supply.
