LCR Meters

Precise impedance measurement for passive components

Chroma LCR meters measure inductance (L), capacitance (C), and resistance (R) of components during R&D, production, QA, and incoming inspection. Component testing often requires much more than a simple resistance, capacitance or inductance value at a given test frequency and stimulus voltage. LCR meters must have the flexibility to provide multiple parameters over wide frequency and voltage ranges.

100Hz-50kHz LCR Meter

Chroma 11021/11021-L

For use in both component evaluation on the production line and fundamental impedance testing for bench-top applications

50Hz-100kHz LCR Meter

Chroma 11022/11025

Programmable test signal level settings are from 10mV to 1V in steps of 10mV, and the VM/IM signal level monitor functions allow you to evaluate your devices at the level you specify

Capacitor Leakage Current/IR Meter

Chroma 11200

Used for both component evaluation on the production line and fundamental leakage current or IR testing for bench-top applications

White Paper: LCR Measurement Primer

What is Impedance? What are the measurements of Impedance? This primer defines and explains the measurement of the impedance parameters known as L (inductance), C (capacitance), and R (resistance). Impedance parameters are characteristic of an AC circuit; this primer describes the impedance measurements that are typically used, including their equations.
