Smart Digital Transformer Resistance Tester Intelligent 3 Phase Simultaneous Winding Resistance Meter Tool with Automatic Temperature Compensation & USB Data Output Connection

Product Description

SX-20A Transformer DC Resistance Tester

The SX-20A Transformer DC Resistance Tester is designed for measuring the DC resistance of transformer windings and other inductive coils. It supports factory inspection, installation, handover testing and preventive maintenance in the electrical power industry.

In addition to winding resistance measurement, the instrument provides practical data management functions for electrical testing departments. Its 7-inch color LCD displays measurement information clearly, while the built-in printer allows users to print test results in real time.

The instrument can store up to 500 test records. Through its USB interface, measurement data can be transferred to a USB flash drive. An RS485 communication interface is also available for transferring test data to a backend system.

The built-in Chinese and English interfaces make the SX-20A convenient for different operating environments.
