Circuit Probe Tester
A circuit probe tester is a tool used to detect and diagnose circuits. We have the following products: V200, V200pro, V210, V500, V500 Pro.

VDIAGTOOL V200 Power Circuit Probe Tester is a simple but extremely useful circuit tester with a 20ft + 20ft extension cord for checking if a car circuit or a component is powered. It supports ✔Tracing wires ✔AC/DC voltage tests ✔Diode, resistance tests ✔Polarity tests ✔Continuity, ground, signal circuit tests ✔Activating components ✔Relay, fuse, trailer light tests ✔Locate shorts ✔Circuit breaker protection for all electrical systems of 12-24V vehicles.

VDIAGTOOL V210 Automotive Open and Short Detector Circuit Tester is powered by 2 9V batteries, it can easily locate breaker points, open connections, broken wires, leakage (tone change), and even trace wires/cables without damaging the insulation. For DIY enthusiasts, electricians and technicians, it is a convenient and efficient circuit instrument that can simply and quickly determine the continuity of cables/wires and diagnose breaker points.

You can quickly and easily find shorts, open connections, broken wires, current leaks and even trace wires. Save yourself time and costly trips to the dealer by purchasing this must-have circuit tester today.

VDIAGTOOL V500 is an intelligent circuit system probe tester that covers all circuit tests:
1. Smart test
2. Multimeter mode (voltage, resistance, diode & short circuit, current, frequency)
3. Relay protection test
4. Oscilloscope mode
5. Injector test
6. 0-5V power supply
7. Component activation
8. Positive and negative detection
9. Diode testing
10. Component testing.
Unlike traditional circuit detectors, the V500 intelligent detection mode can display voltage, current, resistance, etc. at the same time, greatly improving your circuit diagnosis efficiency and saving you time
