Duspol recommendation?

(1/6) > >>

I tried the search function, but nothing turned up - maybe it's because I don't know the english term for this device: A two pole voltage detector for mains testing.

Yesterday while changing a power socket I realized that my old one (a Voltcraft VC-58 LCD) does not function properly anymore: It does still beep when detecting mains voltage, but neither Voltage is displayed nor continuity testing works, so I don't trust this thing anymore. After all my life is on stake. And just to remoind me of that the RCD tripped the same moment I fumbled with the wires (but must have been somewhere else in the house the power was really off in this circuit).

I basically need this only to detect if the the circuit is still live / the correct breaker is off. I also used this to check the rotation direction of three phase current, so I would like this feature if I buy a seperate device. Only household use and only in CATIII 400V. My last one was rated CAT IV 1000V, but I don't need that. I would prefer an honest rating, though. It should of course beep continuously when high voltage is detected since that makes checking the correct circuit breaker easier and also as an additional warning. That part should also work if the battery is empty.

I can read the spec sheets, but don't know how trustworthy the cheaper ones are. I don't aim for 10€ China junk, but don't want to spend the time for a Benning or Fluke for using it a handful of times a year. But I also don't want to use a multimeter, since I don't trust them for this kind of work, they don't work for power sockets with child protection (two probes must be inserted at once with quite some force to reveal the contacts), they are missing the beep function and they are tricky to use in some locations. Also, a screw driver with an led inside has too many failure modes for my taste.

What can you recommend? Is a Uni-T UT18D trustworthy?

Have you searched on 3-phase circuit tester?

Unfortunately searching for "circuit tester" from a US site will not return much that is relevant to Europe.  I searched for 3-phase circuit tester on Amazon and got lots of hits over a large range in price.  For non-contact live circuits, my pencil-like tester from GC (about $12) is still my go to.  In early Spring, I got a Klein for testing and tracing non-energized circuits.  It was about $250, but unless you need to trace for non-energized circuits, I would not waste money on it.

Here are two appealing, medium priced, 3-phase testers from Amazon:

Maybe those links will give you some ideas to broaden your search.

Try "two pole voltage tester" as search term.

As you are located in DE, Reichelt has a lot in their catalogue: https://www.reichelt.de/spannungspr-fer-c5875.html?ACTION=2&GROUPID=5875&START=0&OFFSET=50&nbc=1&SID=95ad2c7d8d86a1c84b6c85000dc5bc920c9f5751b01b1a3577155

If you are not using those testers on a regular basis, I would recommend to look for devices which don't need batteries. I used to have an older Benning Duspol with LCD and continuity test and all the bells and whistles, but the batteries leaked and were stuck in the casing. No way to remove the leaked batteries without destroying the case.

Fungus:
Brymen makes some:

https://brymen.eu/product-category/voltage-testers/

I'd trust one of those far more than I'd trust a Uni-T.


The middle one looks like it does what you need.

Does it really need to beep or is an LED indicator enough?

I would recommend buying a Benning Duspol, but if you do not want to spend that amount of money, I think the PANCONTROL PAN Volttester 400FI is trustworthy. I have one (in addition to my Duspol), it does what it is supposed to do. I have seen the same model under different brand names, but with PANCONTROL, you have an Austrian company where I guess they know what they offer and have tested what they import:

Several sellers offer those, on Amazon you can get one for less than 20 EUR.
