The Fluke 80k-40 40kV probe is for measuring voltages up to 40kV.
It is for use with an AC/DC voltmeter or DMM. It has high accuracy
when the voltmeter or DMM has an input impedenance of 10M ohm +/- 1%
but can work with other impedances (you just have to do more work).
Luckily my voltmeter meets this very requirement. You can see it
in use here in testing my 30kV high
voltage power supply and again here in testing my
negative and positive
high voltage power supply.
Supplier
It's made by Fluke but I purchased it from a local electronics store.
It shouldn't be hard to find as Fluke is one of the biggest name
brands you find in these stores.
The probe connected to my voltmeter. Note the
ground wire with the alligator clip on the end.

Video of the Fluke high voltage probe in use
Here's a video I put together showing me using the probe to measure the
voltage used to fly a lifter. I also take the probe apart to show the
insides.
