Overview
The SZBJ BM818 proves that big things come in small packages. This mini digital clamp meter is engineered for one-handed operation and fits easily into a pocket or small tool kit. Despite its size, it offers high-precision measurement for AC Current up to 200A, AC/DC Voltage, and Resistance. Its standout feature is the NCV (Non-Contact Voltage) detection, which allows you to find live wires inside walls or panels safely.
Key Features
Ultra-Compact Design: Small enough to reach into crowded junction boxes where standard clamp meters can’t fit.
Non-Contact Voltage (NCV): Detects electrical fields without touching live wires; the built-in buzzer alerts you to danger.
Auto-Ranging Precision: No need to manually select ranges; the meter automatically adjusts for the most accurate reading.
Data Hold & Max Value: Freeze your readings on the screen to record data later.
Low Battery Indicator: Never get caught with a dead meter mid-job.
