Tonghui Precision LCR Digital Bridge

Introduction

Tonghui Precision LCR Digital BridgeThe TH283X series is a new generation of low-cost, high-performance compact LCR digital bridge, which adoptsnewThe process and high-density circuit design concentrate the essence of large LCR tester, compact and compact Cancel the traditional mechanical power switch and use software to control the power switch. The basic accuracy of 0.05% and good testing stability can be compared withotherThe model is comparable Equipped with a 4.3-inch LCD display screen and a newly upgraded interface system Beautiful and elegant, easy to operate The instrument provides rich interfaces and is compatible with standard SCPI instructions, making it easy to form various testing systems to meet the needs of inspection, production, and scientific research.
