PicoScope Automotive oscilloscopes
A PicoScope (sometimes known as a labscope) turns your laptop or desktop PC into a powerful diagnostic tool. Think of it as the X-ray machine of diagnostics, letting you see the changing signals inside wires. You can purchase a PicoScope on its own, but most people purchase one of our award-winning Automotive Diagnostics Kits. These money-saving kits contain everything you need – just add a PC.
