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.
