Walfront P4250 Oscilloscope Probe, High-voltage Probe Oscilloscope Probe 100:1 2KV 250MHz Alligator BNC Oscilloscope Scope Clip Probe Test Lead Kit, Digital Oscilloscope Clip Probe

Works great - was skeptical because the lower price - It works perfect!

I was a little nervous about this purchase after seeing some YouTube reviews. For me it works fine. At least I’ve measured line voltage at almost 400 v peak to peak with no issues. I think for low frequency stuff this is a great probe. It compensated easily with my scope. Looks well constructed for the price.

Good for tube amps. Happy with these.

Probes like this can be expensive. These work as advertised in my tests and at a great low price.

I do not need a HV probe very often, so I did not spend a lot of money buying one. I did not see any certification on it, so you are trusting whoever made it, that it is safe to use up to 2,000 Volts. On (low) current limited circuits, I do not worry much about it. For serious HV, most of the time I hook it up to a dead circuit point, step back, and then energize the circuit. If your scope input has a ground common to the probe shield, metal on the oscilloscope can be at the same potential as the probe. So sometimes the best plan is: off-attach-retreat-energize-read-off-safely discharge. Accurate enough for the testing I do. YMMV
