Hantek ignition waveform probe HT25COP — Coil-on-Plug oscilloscope probe with LED and anti-interference

The Hantek HT25COP is a coil-on-plug ignition waveform probe that lets you capture accurate engine ignition signals directly from the ignition coil using a standard oscilloscope.

Designed for automotive technicians and electronics diagnosticians, the HT25COP provides a dedicated signal probe for modern coil-on-plug (COP) ignition systems. It eliminates the need for extension leads or intrusive tapping, combining a compact, ergonomic clip with anti-interference circuitry and a bright LED for clear connection confirmation in low-light environments.

How does the HT25COP connect to a COP ignition coil?

The probe clamps directly over the coil's high-voltage terminal, sensing the ignition waveform without adding long leads or modifying the coil. Its form factor is flexible so you can route it around engine components and maintain a secure contact point during testing.

• Direct clamp-on contact to the coil primary/secondary terminal
• No extension cable required, reducing signal distortion
• Flexible ergonomic body for tight engine bay access
• LED indicator shows successful connection in the dark

Will this probe work with my oscilloscope?

The HT25COP is compatible with standard oscilloscopes and is engineered to deliver a clean ignition waveform to the instrument input. It includes anti-interference design elements that preserve signal fidelity for accurate visual analysis on bench scopes or portable diagnostic oscilloscopes.

• Direct output suitable for common oscilloscope input ranges
• High-accuracy measurement circuitry to reduce noise
• Works with both benchtop and handheld oscilloscopes
• Connector and cable interface designed for secure oscilloscope hookup

What features help capture reliable ignition waveforms?

Several design choices make the HT25COP effective for repeatable waveform capture: an anti-interference layout to lower electrical noise, an ergonomic clip that maintains contact during engine vibration, and a visible LED to confirm connectivity. These elements together reduce troubleshooting time and improve confidence in waveform interpretation.

• Special anti-interference design for clearer signals
• Ergonomic clip can be curved to fit various coil shapes
• Bright LED for nighttime or under-hood visibility
• Robust construction for repeated shop use

How do I use the probe safely in a vehicle environment?

Always follow standard safety precautions when probing ignition circuits: the engine should be accessible and stable, wear insulated gloves if needed, and avoid contact with moving components. The HT25COP reduces risk by providing a non-invasive clamp and secure connection so you can keep hands clear of hot and rotating parts while capturing data.

• Clamp on coil while engine is off for setup, then run engine for live capture
• Keep probe cable routed away from belts, fans, and hot surfaces
• Use oscilloscope ground properly to prevent grounding issues
• LED helps verify contact without prolonged visual inspection

Who is this for? The Hantek HT25COP is built for automotive technicians, diagnostics specialists, and electrical engineers who need reliable ignition waveform capture from modern coil-on-plug systems. It is particularly useful in professional workshops and mobile diagnostics where quick, accurate oscilloscope readings are required without modifying the ignition system or adding bulky leads.
