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

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.

This is one of the durable standards for this type of tester.

Serves the purpose of checking Amperage but can be a little awkward

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.

I used this to measure the rush current on one my outlets using the clamp meter. This tool allows me to hang the clamp on one of the leads to get measurement. I was able to get reading without opening up the wall outlet. Its really easy to use and the GFCI tester is also handy for testing GFCI outlet function.

Very useful to avoid breaking into a 120VAC plug product to measure current.

Handy tester and cheap enough to just use as a branch circuit pilot light. I use one in each of my greenhouses and at night I can see the LEDs from the house to confirm that power is still on for the electric heaters after the lights go off.

Includes 1x and 10x inductive current monitor loops built in. What I really wanted. 4 time larger than the standard GFCI tester.

Ok, these devices are not rocket science. If all you want to do is read AC current, you could easily separate the two wires in an AC extension cord and clamp your clamp current meter around one of the lines. This would give you exactly the same result. Want “times 10”? loop one of the lines 10 times, and then clamp around that loop to read 10 times the current. But the ET100 will also give you indications that your wall outlet is wired correctly or not. It also has the ability to check your outlets GFCI breaker. For the price, this is a handy tool to have in your box if you want to measure AC current or quickly check an outlet. It seems durable and well built, but I just recently received it so I can not comment on long term durability

This Splitter and GFCI Outlet / Receptacle Tester works great. My only complaint is its length, its just a little too long.
