HT30A+ HT201 Hantek Oscilloscope Accessories Set BNC Connecter Auto Test Leads, Auto Ignition Probe and 10MHz 20:1 Attenuator for Assisting Automobile Measurement

The HT30A Automotive Test Lead – A Must-Have for Mobile Diagnostics ​If you’re moving from basic electronics into automotive oscilloscope work, the HT30A is arguably the best "bang for your buck" upgrade you can buy. It solves the biggest headache of vehicle diagnostics: reach and cable clutter. ​### Why it’s a Game Changer ​The 3-Meter Advantage: Most standard scope probes are too short to reach from the engine bay to a laptop or scope sitting safely on a workbench or rolling cart. At 3 meters (nearly 10 feet), this lead gives you the freedom to move around the vehicle without dragging your expensive equipment toward a hot engine or spinning fans. ​Built for the Shop: Unlike delicate bench probes, the HT30A is thick and "heavy-duty." It feels like it belongs in a garage. The shielding is surprisingly good for the price point, effectively blocking out the EMI (electromagnetic interference) generated by ignition systems and alternators that often ruins cheaper signals. ​Smart Design: I love that the ground and signal leads at the end are different lengths. It seems like a small detail, but it prevents the clips from tangling or accidentally shorting against each other while you're trying to back-probe a tight connector. ​Universal Compatibility: Since it uses a standard BNC connector and 4mm banana plugs, it works with almost everything—Hantek, PicoScope, Owon, or Siglent. It’s the "universal adapter" of the automotive scope world. ​### The "Pro" Setup ​For the best results, I highly recommend pairing this with a 20:1 Passive Attenuator (like the HT201). This allows you to safely measure high-voltage signals like fuel injectors or primary ignition without risking your oscilloscope's inputs. ​Bottom Line: If you are doing professional-level diagnostics on a DIY budget, don't waste time with short, flimsy leads. The HT30A provides the reach and durability you need to get clean waveforms every time.

Great product

Good value for the money

Even though this has a cheap price, compared to other leads, it works great with my pico!

Cable cam apart in under a year and I reached out to Hantak and they never responded back to me.

All good delivery the items , thanks 😊

I bought 2 sets of cables and both came apart after maybe using them 5 times. Like another reviewer said, there’s a screw that holds the positive terminal inside the banana plug and it comes loose. Thankfully I was able to open up the connector and retighten but I also added a little bit of solder to make it harder for it to come loose again. I used a Fluke multimeter to check continuity on the cable and it’s 0 ohms. I hope 🤞 it stays tight for a long time. If you are looking for really good quality then keep looking but if you know how to repair things and don’t want to pay too much the get these but don’t expect them to be amazing quality.

Vraiment très bon produit. J’en ai pris deux et j’en prendrais deux autres quand je passerais sur un score à 4 voies.

The cables are decent-quality and long enough to handle any car diagnostic task, and the attenuator performs its job perfectly. Overall, it offers excellent value for money.

Great price, Great product, bought 2.

J'ai acheté 2 cables HT30A. Pour l'un tout fonctionne bien. Par contre, sur le deuxième le signal est aléatoire. Il est donc imposible de l'utiliser de manière fiable avec l'osciloscope si on ne peut pas faire confiance à ce qu'on va lire. Si on bouge le fil à proximité du connecteur BNC, on peut voir le signal s'afficher ou disparaitre. Vue d'extérieur le cable n'est pas endommagé. Il doit y avoir un souci de connexion interne.
