Works fine
Seems to work fine. Can't check calibration exactly, but it reads very close to a 5kV analog meter on my hipot tester.

It really is accureate!
Have always needed a high-voltage probe but made do with a 470 Meg resistor from my junkbox and some math. However the reasonable price of this item (compared to the big names) pushed me over the edge and I 'm happy for it! Accuracy of the probe itself is better than 1/2% as confirmed be measuring a moderate voltage directly with my 4-1/2 digit DVM on the Volts scale then measuring it again with this probe on the mVolts scale and the readings agreed perfectly!

Design Changes
About right for price, but would be wiling to pay twice the price with a variable user slectable voltage splitter ratio in several increments to less than 1000:1 from 40 kv. Also, with a probe that is a flexible shaft instead of rigid; also, with a slightly larger

Great HV probe - Big!
This absolutely gets the job done. It's a lot bigger than the photo would imply- about a foot long. It comes with a couple different tips, and the cord fits all three of my multimeters, so no problem there. I would buy this again- it works great, and I haven't gotten shocked.

Measures accuratly and working fine
Used it to diagnose my electrostatic air filter. Found the high voltage transformer not working. Replaced and verified the correct voltage working.

2 out of 5 is bad
Why did you pick this product vs others?: Works good when it’s working , but most the time it won’t read anything not sure if I go a dud or not but I can’t return now as it’s out of the window. I would say test as soon as you get it

looks good and works
Arrived and works as expected
