Introduction

TH2817B + is a compact LCR digital bridge launched by Tonghui. Its test frequency ranges from 50Hz to 100kHz (11 frequency points available for resolution), featuring 0.1% basic accuracy and maximum 19ms test speed. It supports 10-bin sorting, multi-frequency list scanning and other functions, adapts to 110V/220V power supply, and provides efficient and accurate parameter testing solutions for scenarios such as quality inspection in electronic component production and laboratory R&D.
