Dual-Channel Handheld Oscilloscope

There are times when fault code information alone is not sufficient to diagnose a vehicle fault, and this is where an oscilloscope becomes an invaluable part of your automotive toolkit.

The Sealey TA220 Dual Channel Oscilloscope enables the output of a wide range of vehicle electrical and electronic components to be checked graphically against reference waveforms for rapid diagnosis.

The sampling rate on this scope is sufficiently high to detect CAN bus signals.

Additional information

This oscilloscope is designed to sense electrical signals directly from electronic components on the car.
It is not a diagnostic fault code reader, and so will not read/clear codes from your vehicle or reset "service due" indicators.
