Hantek HT25 Auto Ignition Probe Oscilloscope Accessory 2.5m 10,000:1

Description

Product Overview

The Hantek HT25 Auto Ignition Probe is engineered as a high‑performance inductive capacitance sensor specifically tailored for automotive ignition system diagnostics. With a generous 2.5 meter lead length, the probe provides ample reach to connect comfortably to spark plug wires while maintaining signal integrity. Its core design incorporates a 10,000:1 decay attenuation ratio, allowing the oscilloscope to capture fast transient events without overload. The probe features a three‑point connector system: a BNC‑compatible joint for direct oscilloscope attachment, a secure clip for easy placement on ignition leads, and a grounding clip that safely diverts high‑voltage spikes. Constructed from durable, heat‑resistant materials, the HT25 endures the harsh environments typical of engine bays, including exposure to oil, vibration, and temperature fluctuations. The product dimensions of 6.61 × 5.51 × 1.14 inches and a lightweight 5.29 oz design ensure it can be stored conveniently in toolkits and deployed quickly during troubleshooting sessions.

Usage

Designed for professional mechanics, automotive engineers, and serious hobbyists, the HT25 excels in a variety of real‑world scenarios. Whether you are diagnosing misfires, verifying timing accuracy, or analyzing coil performance, the probe delivers clear, high‑resolution waveforms that reveal subtle irregularities in spark behavior. Its non‑intrusive clipping method allows you to attach the sensor to the insulated portion of the spark plug lead, eliminating the risk of direct contact with the high‑voltage tip and preventing accidental discharge. The probe is also suitable for educational settings, where students can observe ignition events in a controlled laboratory environment without compromising safety. When used with any standard oscilloscope that accepts BNC inputs, the HT25 translates the high‑frequency ignition signal into a manageable voltage range, making it easy to interpret results on the screen. For best performance, maintain a minimum clearance of two inches from other high‑voltage components to avoid interference, and always verify that the test clips are securely fastened before powering the engine.

FAQ

Can the HT25 be used with any oscilloscope?

Yes, the probe features a standard BNC connector that fits most bench‑top and handheld oscilloscopes with a BNC input. Ensure the oscilloscope’s voltage range matches the probe’s attenuation settings for optimal results.

Is it safe to clip the probe directly onto a spark plug?

No. The probe should be attached to the insulated portion of the spark plug lead, not the plug tip itself. Direct clipping can cause arcing and damage both the probe and the ignition system.

What maintenance is required for the HT25?

Periodically inspect the clips and connector for wear or corrosion. Keep the probe clean and store it in a dry environment. Calibration is not required for normal use, but you may verify attenuation accuracy with a known reference signal if desired.

How does the three‑point connection improve measurement accuracy?

The three‑point system separates the signal, ground, and reference paths, reducing noise pickup and ensuring a stable baseline. This configuration helps capture the true shape of the ignition waveform without distortion.

What warranty does Hantek provide for the HT25?

The HT25 comes with a one‑year limited warranty covering manufacturing defects. Contact Hantek support for warranty claims, replacement parts, or technical assistance.
