Overview
The SZBJ BM818A (often part of the 800-series family) is designed for the everyday electrician. It provides a non-invasive way to measure AC Current up to 400A, meaning you can check the load of an entire house or a heavy-duty air conditioner without stripping a single wire. Its rugged, ergonomic body is built to survive accidental drops, and the clear LCD display makes it easy to read even in low-light conditions.
