12V 0.01~19.99A Car Circuit Tester – Precision Automotive Diagnostics
High-precision galvanometer measures current from 0.01A to 19.99A with 0.01A resolution for pinpoint accuracy in diagnosing electrical faults. Durable ABS housing with shock-resistant design and reinforced probe tips for extended use in tight engine compartments or harsh workshop conditions. Simplifies fuse testing, parasitic drain checks, and alternator performance verification – no multimeter setup required. Backlit LCD display ensures clear readings in low-light garages or roadside emergencies. Integrated fuse protection prevents damage to vehicle circuits during accidental overloads. Universal compatibility works with 12V systems in cars, trucks, motorcycles, and marine applications. Compact pocket-sized design stores easily in toolkits for mechanics or DIY enthusiasts. Direct-read amperage bypasses complex calculations – ideal for quick troubleshooting of stereos, lighting, or battery drains. Industrial-grade copper alloy conductors minimize resistance for reliable long-term performance. Includes protective rubber boot to prevent scratches on delicate automotive finishes.
