Voltage Detector Pen Non Contact Electrical Tester Pen Multimeter 600V NCV with Adjustable Sensitivity AC DC Voltage Ohm Capacitance Continuity Diode Live Wire Tester Circuit Checker

First off I would never trust any of these proximity testers with my life. These are a useful double check before you lay your hands on anything that may prove to be your last. Basically, once you have isolated the power tested with an actual proper multimeter then this provides a useful second test. In the marine industry on ships and offshore it's mandatory to use one as this double check.Of course the other use is for checking for fault finding and testing. You might be tracing down a line and it's good to be able to do a quick and dirty check to see if power is there. It can make working out where there is a problem on a power circuit a bit faster.Inevitably, one has to compare this with the Fluke which has been around for a decade or so. I've used loads of them and have a couple in various kits. Like this one, it's not the only thing I would rely on especially with my life, but a useful extra. Anyway, I prefer this one by far.Firstly it has a really easy to read display showing the strength of the voltage picked up so you can judge it a little better. It has an audible alarm as well just like the Fluke. In use I found it to be just as reliable and to be honest with the visual indication a bit more trustworthy because you can see the EMF strength it's picking up.There are some downsides. It's a bit more complex and because of the screen and buttons a little less robust than the Fluke.There is one bonus of course in that you get the ability to use test leads to get a direct measurement of the voltage when possible thus this is part way to being a multimeter as well.Overall, a very useful electrical tool box addition and I'm genuinely pleased with it.

bought as a DIYer. Seems easy to use i like the case should last me years

It appears to do everything it is intend to. My only comment is the quality of the operating instruction is poor

The unit is a compact, easy to read meter. This would have been top of my list for simple easy to use multi meters.However, it was the NCT (non-contact testing) that I was after, to do quick simple tests. Unfortunately I could not get reliable readings at any metal-clad installation, and it was detecting voltage in the air when on high sensitivity and standing near a 240v AC T0 24v DC voltage transformer. Problems with readings between live, null and earth on plastic fronted sockets on both sensitivity settings.It may be I got a faulty unit, even possible I was using it wrongly. The instruction manual is basic (English is poor).On the positive side, the multi meter is excellent, the size of the unit and simplicity to use is excellent and I was tempted to keep it for that alone, but I already have 2 Flukes, and a cheap meter for jobs I don't want to risk damage to the flukes.

I have used "cheap" non-contact devices before and they were always a little erratic in their detection abilities. My last one just stopped working so went into the bin.This new, more "expensive" version seems to be able to detect an electric field about 58cms away on "sensitve" and about 7cms away on "normal". It also detects cables behind 18mm MDF but not in walls or behind metal face plates.The LED light projects a small focussed light that allows you to walk down steps in complete darkness or see areas in the back of a cupboard. It's not a torch, but enough light to see what you are doing.The other functions are a little "laggy", taking a few seconds to settle on Ohms or Voltage, but hey, this is only a pencil device, I have a meter for better readings. I would have preferred a single lead and a probe on the device rather than two leads, but again, it's a non-contact detector with other functions so it can be forgiven.It comes in a decent case with enough room for a couple of small screwdrivers, so all good there too.The only downside is... the instruction book which could be better in respect to operation of device in situation of use when usageing. But hey, it was a reasonable cost and works and has a decent case and a torch and a beeper for continuity and a scale for how much electrickery is being detected and can be turned off to save the battery. What more do you want?

My first meter... needed it to test the wiring in some lamps that suddenly stopped working. Quickly discovered the fault and rectified. Handy tool to safely check mains power supply. Many other uses but I have yet to trial them.

Small and light. Can hold in hand while testing. Comes in a small hard case. Good clear screen. Ideal portable tester. Seems accurate enough for mains and plc work. Ideal.

It's OK not sure on the accuracy ?
