TopDiag P200 Pro Circuit Tester – Power Probe, Relay & Fuel Injector Tester, Oscilloscope

This thing is a toolbox on its own.

The TopDiag P200 Pro is a heavy-duty circuit tester that does way more than just check for power.

It can test relays, fuel injectors (and even clean them!), components, and it has multimeter and oscilloscope modes.

It measures voltage (2mV-100V), current (3mA-25A), resistance, and frequency.

Works on 9-48V systems—so cars, motorcycles, even some trucks.

Latest hardware and software, CE certified, comes with a 1-year warranty.

If you're serious about electrical diagnostics, this is your new best friend.
