Keysight LCR meters

E4980A & U1730C series LCR meters and impedance measurement products

The best combination of accuracy, speed and versatility for a wide range of component measurements.

Supplier: Keysight Technologies

Technology type: Impedance, Capacitance and LCR Meters

The E4980A-series bench LCR meters meet your impedance measurement needs in the field of R&D, production, quality assurance, or incoming inspection. They provide the best combination of accuracy, speed, and versatility for a wide range of component measurements.

The U1730C-series handheld LCR meters allow you to measure frequencies as high as 100 kHz, a capability typically found only in benchtop meters. Get measurements done faster using the one-touch automatic identification function button which displays component type and more detailed component analysis such as Z, ESR, and DCR. Ideal for testing on the go, these LCR meters operate on a battery that lasts up to 16 hours.
