ET1090/ET1091 Benchtop LCR Meter for Component Measurement

Short Description:

ET1090 and ET1091 series LCR digital bridge is a component parameter analyzer based on the principle of automatic balancing bridge. Its 10Hz-100kHz test bandwidth, frequency continuous adjustable, 0.2% basic measurement accuracy and the file classification function provided by the instrument provide accurate and complete measurement and analysis for most components and materials, which are widely suitable. Used in product development, component inspection, product on-line inspection and other applications.
