Precision Digital LCR Meter TH2819A
Introduction
TH2819A is an updated product of TH2819 LCR meter with the features of TH2819, including easy operation, accurate and stable reading. It has smaller size than TH2819, nice appearance, and low cost.
With test frequency from 20Hz to 200kHz, frequency resolution of 10mHz, wide test signal level range from 5mV to 2V, measurement speed up to 32ms/time, TH2819A can be used to inspect electronic components, not only for measurement parameters TH2819 has, but DCR measurement. The meter has 1.5V/2V internal bias voltage, optional ±10V (±100mA) and 1A internal DC bias source and external inductance bias sources to inspect inductive components.
With high speed, wide test range, and 6-digit resolution, TH2819A can be used in quality control on production line, incoming inspection and lab measurement.
