ST2840 Series Precision LCR Meter

ST2840 series pricision LCR meter innovatively adopts a new generation of technologies such as dual CPU architecture, Linux bottom layer, 10.1-inch capacitive touch screen, built-in instruction which effectively solves the defects of slow LCR test, single display and complicated operation in the past.
The measurement frequency of ST2840 series is from 20Hz-500kHz/2MHz, which makes up for the shortcoming of lack of high-performance bridge in the frequency range of 500kHz.
ST2840 series LCR meter adopts four-parameter display, all settings, monitoring, sorting parameters, status, etc. can be displayed on the same screen, avoiding the cumbersome operation of frequent switching.
