Overview
The SZBJ BM528D is a powerhouse diagnostic tool engineered for high-voltage and high-current applications. With a massive 1000A AC measurement capability, it is specifically designed for the “High Power” sector. Its oversized jaw allows it to clamp around thick industrial busbars and heavy-gauge cables that standard meters simply cannot accommodate. If you are troubleshooting industrial air conditioning plants, factory machinery, or grid-level solar installations, the BM528D provides the range and reliability you need.
Key Features
1000A High Current Range: Capable of measuring massive AC loads across three ranges (20A / 200A / 1000A).
Industrial-Sized 55mm Jaw: One of the largest jaw openings in its class, designed for thick power cables and busbars.
Dual Voltage Testing: Accurately measures both AC and DC voltage up to 600V/1000V for comprehensive system checks.
Resistance & Continuity: Includes a built-in buzzer for quick continuity testing and resistance measurement up to 2000MΩ (with optional insulation tester).
Data Hold & Peak Value: Easily capture and freeze readings in high-stress environments.
Rugged Housing: Built with a drop-resistant outer shell and a comfortable ergonomic grip for field use.
