MEASUREMAN Electrical Test Kit, Non-Contact Detector, AC Voltage Tester Pen/Socket Tester, GFCI Outlet Tester, Live/Null Wire Judgment

Not really surprised with the results, but this is a very useful tool to have. A cheap but very nice investment. It allowed me to determine why my UPS was throwing a wiring fault instantly.

Very easy to use

This is a very useful little tool. Easy to use...nothing difficult about it. You dont need to be an electrician, but if youre in facilities maintenance...this is the gadget for you.

A good combo tool to test AC voltage, one is to test the socket/outlet while the other one is a non-contact to test the presence of AC voltage. * socket/outlet tester It is very nice to have the voltage digitally display, with backlight, it also does the job, able to identify the correct and one socket which is open neutral, however, the indicators LED are ALL RED, no matter it is just open or the more serious condition - reverse. Comparing to the traditional one I have, it uses two colors where the red indicates the more serious reverse and the two amber lights for normal or open wire. So, the 3 red colors approach is slightly confusing and need to read up the chart to know whats wrong. Finally, there is a little button to trip the GCFI outlet to make sure it works, it works properly. Forget to mention, this socket/outlet tester WILL BLOCK the usage of the other one, which means the other socket needs to be emptied, while my traditional one just occupy one outlet and wont block the other outlet(either upper or lower). * non-contact AC voltage detector It has two modes, one is more sensitive upon hitting the button, real sensitive that even about more than 2 inches can detect the live AC voltage. It helps me in identifying where the AC voltage stop in one of my hanging christmas light and able to pinpoint which LED bulb is malfunction, good job! However, its also funny that it has false-positive alert on my ipad being charged with AC voltage. It is charging by 5V DC, where is the AC? Overall, both tools work upon detection the presence of AC voltage, there is a false-positive, but its good that no false-negative(where you have live AC voltage but your tool cant detect it). So, I would still use both tools for AC voltage testing.

Good quality and works well

Im happy work just as good as Klein tools

Great for testing sockets

This is an awesome tool to have for all handy people. Even though I have a very nice multi-meter, trying to stick probe in an outlet can be a challenge from different angles esp those with safety covers built in. This replace my standard plug in recepticle tester except that it give a voltage reading in addition to polarity checking. Just wish it was a little smaller. The NCV pen tester is also great and as good as the plastic klein tools ones from home depot, but easier to read and use. I would not sit on it though. Would gladly pay more if they had a slightly more durable version that can be sat on or dropped.

I have the peace of mind KNOWING there is no power going to a plug Im about to replace.

Lo estoy usando para verificar tomas en mi casa ya que cambie todos mis plugs
