China Partial Discharge Testing Machine Portable Jfd-2000A Ultrasonic Pd Detector

In order to rapidly develop the market and realize the industrialization and scale of astm d445 Kinematic Viscometer, astm d86 distillation tester, Interfacial Tension Meter, we continue to create and improve the products, with the goal of shortening the product design cycle and reducing development costs. We face up to the increasingly fierce market competition, bring our subjective initiative to the maximum, so as to create a characteristic development path. We hope to give excellent talents a broad space to display, give potential talents sufficient growth support, and give outstanding talents excellent returns.

HZJF-9041D Four Channels Partial Discharge Detector

Overview

The HZJF-9041D four-channel partial discharge detector is a new type of digital partial discharge detection device developed by our company. While retaining all the advantages of the HZJF-9041 model, this product further reduces its size and optimizes its performance. It replaces the traditional oscilloscope and physical knob operation with a 10.1-inch touchscreen, making it more convenient to use.

This instrument features a fully touchscreen operation design, which not only enhances operational durability but also includes the following functions: one‑click automatic calibration, adjustable high‑voltage test divider ratio, and support for uploading test data via serial communication. The device offers high sensitivity, a wide range of applications, a broad dynamic range of the amplification system, multiple frequency band combinations (nine types in total), and strong anti‑interference capability. It is a practical partial discharge detection instrument widely used by power departments, manufacturing enterprises, and research institutions.
