HUAREW Car Circuit Tester – Real-Time 0.01–19.99 A Current Meter, 20 A / 48 V Max

Overview

Meet the HUAREW Car Circuit Tester, a compact, durable tool designed for automotive electrical diagnostics. It plugs into a fuse socket to read live current and helps you understand circuit behavior at a glance. It supports brief bursts up to 20 A at 48 V.

Real-time Readings You Can Depend On

The built-in LCD provides a high-contrast, real-time readout, capturing small fluctuations so you can quickly identify potential issues. The display clearly indicates whether the current is positive or negative in DC, helping you map circuit flow with confidence.

Precision and Range

With a measuring range of 0.01 A to 19.99 A, this tester emphasizes accuracy for automotive electrical work. The clear readings support informed maintenance decisions without guesswork.

• Real-time Reading: the LCD shows current values with responsive updates for quick checks.
• Precision: 0.01–19.99 A range enables fine-grained measurements in car circuits.
• Easy to Operate: follow simple steps to connect the tester into the circuit while maintaining protection.
• Portable & Illuminated: lightweight design plus built-in lighting for dim spaces.
