I have used it to check the HV output of a microwave and neon transformers. Be careful. Use one hand to measure and the other hand in your pocket. **Q: Can this be used with oscilloscope to measure ac beside 60hz sinusoidal? what is bandwidth?** A: I suppose it could, though the signal could potentially be noisy. The leads are not shielded. You would also have to correct the impedance. This probe uses a simple voltage-divider resistor network to do its magic. Good luck! **Q: Could this be use to probe the residual high voltage in a CRT monitor (and to dissipate it)?** A: Yes, definitely. The probe's input resistance in 1G-ohm (1000 M-ohm). With a typical 500pF filter capacitance in the CRT HV power supply, the discharge rate will be 0.5 seconds to discharge to 37% of the original voltage, 1 second to 37% of that, etc. After 5 seconds there will be only a couple of volts remaining. BE SURE to attach the ground clip to the metal chassis of the CRT device whether or not the probe is connected to a meter. To be completely safe, wait a minute after discharging then repeat the process. The glass in the CRT "absorbs" some charge and can recharge the filter capacitor to a few hundred volts. **Q: can it measure 12 volt vehicle ignition coils?** A: I could not say for sure. But the probe does indeed measure DC voltage up to 40,000 volts. So you should be able to set your meter that you have the probe plugged into and make the measurement, by setting your meter to read DC volts. (not AC volts) Obviously you're only dealing with 12v on automotive voltage. ## Frequently Bought Together - EX ELECTRONIX EXPRESS High Voltage Probe 40,000 Volts Max DC, 28,000 Volts Max AC (50/60 Hz) Red, Black - onelinkmore BNC Male Plug to 2X 4mm Dual Banana Female Jack Socket Binding Post RF Coax Coaxial Splitter Connector BNC Banana Adapter for HF Radio Antennas Oscilloscope DVM Pack of 5 - Goupchn Oscilloscope Clip Probes 200MHz Fully Insulated BNC End Probe with Accessories Kit 1X 10X --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.lk/products/170464798-ex-electronix-express-high-voltage-probe-40-000-volts-max](https://www.desertcart.lk/products/170464798-ex-electronix-express-high-voltage-probe-40-000-volts-max) --- *Product available on Desertcart Sri Lanka* *Store origin: LK* *Last updated: 2026-05-12*
