P100pro/P200 Multifunction Automotive Circuit Tester - 12V/24V DC Voltage Detector, Polarity and Continuity Tester for Electrical Diagnostics - Compact & Portable

Unravel the maze of your vehicle's electrical circuits in an instant! The P100pro/P200 circuit tester is the essential, fast, and reliable tool for identifying common electrical problems in cars, vans, motorhomes, and boats. Compact, robust, and 12V/24V compatible, it's the perfect companion for experienced mechanics, breakdown technicians, and DIY enthusiasts.

Why is this tester essential for your workshop or toolbox?

Fast Electrical Diagnostics & Versatile:

DC Voltage Detection: Instantly identify the presence of voltage (12V or 24V) and check fuses, relays, switches, and wiring.

Polarity Check: Safely determine the positive (+) and negative (-) terminals on batteries, trailer plugs, or accessory cables.

Continuity Test: Quickly check if a circuit or cable is open or intact, with a clear audible and visual signal.

Signal Simulator: (Depending on model) Generate signals to test the operation of flashing lights, horns, or small actuators.

Professional & Practical Design:

Wide Power Supply: 12V & 24V DC. Use it directly on your car battery (12V) or truck/RV battery (24V) without an adapter.

Ultra-compact and lightweight: Only 23.5 cm long and 0.35 kg. It fits in the palm of your hand and stores in any glove box or tool kit.

Robust and reliable: Reinforced housing resistant to shocks and workshop environments. Long test cable with a high-quality probe and a sturdy alligator clip.

Clear indication: Different colored LED lights and an audible buzzer for unambiguous results, even in noisy or poorly lit areas.

Maximum ease of use:

No batteries required!

It connects directly to the source being tested.

Simple interface with a single rotary selector to choose the function (DC Voltage, Polarity, Continuity, etc.).

Main applications:

Quickly locate a blown fuse or open circuit.

Diagnose lighting problems (headlights, brake lights, turn signals).

Check a battery's state of charge and cable polarity before jump-starting.

Test trailer sockets (lights, brakes).

Troubleshoot electrical accessories (car radio, power windows, power seats).

⚠️ Safety and Precautions:

This tool is designed for low-voltage vehicle circuits (up to 24V DC). Do NOT use it on mains power (110V/230V AC).

A basic understanding of automotive electrical circuits is recommended for optimal and safe use.
