Hantek HT25COP Coil-on-Plug Ignition Probe — Flexible Ergonomic Shaft, Anti-Interference LED

The Hantek HT25COP is a coil-on-plug ignition waveform probe that plugs directly onto ignition coils so you can capture accurate engine coil and spark signals with a standard oscilloscope.

If you diagnose ignition systems or develop automotive electronics, the HT25COP gives you a non-intrusive way to read coil-on-plug (COP) signals without adding long extension leads. Designed to work with conventional oscilloscopes, this probe emphasizes anti-interference circuitry, a flexible ergonomic body that conforms to tight engine bays, and a built-in LED to help you position the probe in low light.

How does the HT25COP capture coil-on-plug waveforms accurately?

The probe makes a direct contact with the ignition coil so you measure the waveform at its source rather than through long cables that distort the signal. Internal shielding and anti-interference design reduce noise so the oscilloscope records clean, repeatable traces for analysis.

• Direct contact tip that avoids extension leads and added capacitance
• Special anti-interference circuitry for clearer waveforms
• Compatible impedance for connection to ordinary oscilloscopes

Can I use this probe with my existing oscilloscope?

Yes — the HT25COP is built to work with standard oscilloscope inputs so you don’t need a specialty instrument. Simply attach the probe to the coil and connect the probe’s output to your oscilloscope channel to begin capturing ignition events.

• Works with typical bench and handheld oscilloscopes
• No special adaptor or extension cable required
• Preserves signal integrity for accurate time and amplitude readings

What features make the probe easy to use in tight engine compartments?

The HT25COP’s body is ergonomically shaped and can be bent or curved to reach coils in cramped spaces without stressing the connection. A built-in LED highlights the contact point so you can ensure proper placement even when visibility is poor.

• Flexible, bendable probe shaft that conforms to confined layouts
• Ergonomic design for single-handed positioning
• Integrated LED illuminates the contact area for nighttime work

What practical checks can I perform with this probe?

Use the probe to verify primary and secondary ignition timing, detect misfires, and compare coil firing patterns across cylinders. Clean, low-noise traces simplify baseline setting and troubleshooting so you can make quicker repair decisions.

• Compare waveform shapes between cylinders to spot weak coils
• Measure dwell and spark duration for ignition timing checks
• Capture transient spikes and noise that indicate wiring or grounding issues

Who is this for: The Hantek HT25COP suits automotive technicians, diagnosticians, electronics engineers, and hobbyists who need reliable coil-on-plug signal access without modifying the ignition system. If you frequently analyze engine ignition behavior with an oscilloscope or need repeatable, low-noise waveform captures inside cramped engine bays, this probe streamlines setup and improves measurement fidelity.
