Precision Diagnostics for Every Vehicle and Machine
One diagnostic approach for everything you work on. From passenger cars, vans and motorcycles to tractors, trucks, excavators and outboard engines, PicoScope turns complex signals into first-time fixes on the road, in the field, on-site or at sea.
One Fault. Many Machines.
The Same Problem, Whatever You Diagnose
Every sector faces the same core challenge. Fault codes tell you where a problem is logged, not why it is happening. Modern vehicles, machines and vessels run on complex electrical, hydraulic and communication systems, and the intermittent faults cost you time and money. So, whether it’s a car with a network dropout, a tractor down at harvest, a truck losing a day off the road, an excavator hunting under load or an outboard that will not start dockside - they all share one need: evidence-based repairs, not guesswork.
Why Choose PicoScope?
One Tool. Every Signal.
A scan tool reports symptoms. A PicoScope Oscilloscope shows you the underlying electrical, mechanical, hydraulic and timing behaviour behind the code, so you replace only what is faulty and prove the fix. With intuitive PicoScope 7 Software, Guided Tests and a Waveform Library with thousands of captures to benchmark against your findings, it is easy to use and even easier to embed in your current diagnostic workflows. Our scopes are also USB-powered, making them compact and portable, so your diagnostic expertise goes wherever the fault is, whether that’s at the workshop, in the field or quayside.
The Most Trusted Name In Diagnostics
We have built industry-leading measurement tools since 1991. Today, PicoScope is trusted by diagnostic professionals across many industries, from automotive to agriculture, truck, construction, and marine, covering independent workshops and global manufacturers alike.

Frequently asked questions
Yes. The same PicoScope Automotive Oscilloscope and PicoScope 7 Software diagnose cars, trucks, agricultural and construction machinery as well as marine engines. The signals differ by application, but the method is the same, and Guided Tests and accessories adapt the scope to each job.
A scan tool reads fault codes and reports where a problem is logged. An automotive oscilloscope captures the live signal and shows how a component actually behaves, so you can confirm the real cause of a problem before replacing any part. Most technicians use the two together, with the scope as a verification step.
The core oscilloscope stays the same. Some applications add accessories, for example high-voltage kits for EV and hybrid work, pressure transducers for engine and hydraulic testing, current clamps for 24V systems, and accelerometers for noise and vibration.
