Triplett AC Line Splitter and GFCI Outlet/Receptacle Tester with 5 Visual Indicators (ET200)

This little gadget is a life saver for determining polarity

Does the job and then some.

Unless you own a tiny clamp meter, you wont be able to clamp onto the 1X hole as it is WAY too small. Of the 5 clamping meters I own, not one of them could fit through the 1X hole. Although I do not mind having to divide by 10 to get the valid amps, I can get a 10X splitter a lot cheaper than the $20 for a feature I can not even use. Poorly designed.

If your looking for a cheap good plug tester, this works great. It is a simple device and there isnt much to it, but mine has taken a beating over the past week an it works great, even after 15ft falls.

just plug in and clamp on your clamp meter. 10X helps for small currents

Used once to check amperage of a sump pump during operation with my Clamp multimeter. Measurement was plausible, most likely correct. Used GFCI tester per instructions provided. Worked well. A convenient way to perform this type of testing if length of the device lets it fit where you need it to be.

So easy to use the graphics right on the plug

Saved a lot of time replacing all outlets in house

A good addition to any tool box.

Well, it’s super tough to get a heirloom quality tool these days, so don’t expect that. But this essential tool works well enough. 4 stars for accuracy. Both the 1X and 10X slots should read the same (decimal point should just be moved over 1 place), but they are 3/10ths of an amp off from each other at 12 amps. That’s not too bad, but it’s not what it should be.
