Neoteck Voltage Tester/Non Contact Voltage Tester 12-1000V/48-1000V Adjustable Sensitivity AC Voltage Detector Tester Pen Live/Null Wire Tester with LCD Display Buzzer Alarm Wire Breakpoint Finder

Like it, work very well, highly recommend !

Very easy to use, good quality and easy direction!

This definitely tells me if a wire has power flowing through it. When there are multiple wires near each other (like running through joists), it's hard to tell which one it's detecting. Sensitivity is pretty good on the normal level, and VERY sensitive on high. Good value for the price

I needed to install new GFCI outlets in my kitchen and wanted to use all safety precautions. I used this tester to confirm the electrical circuit was off while changing the outlets. This is an excellent, easy to use tool.

This worked great for me when I was installing my washer and dryer. It helped me see if the voltage was enough when I installed a new outlet. I will keep this around for future projects.

It is a nice non-contact voltage tester and feels sturdy for the cost. It is rather sensitive which makes it harder to pinpoint cable breaks or troubleshoot Christmas lights. It would be nice if you could adjust the sensitivity. I did correct several Christmas light and wire problems with it. You just have to shield off the wires or bulbs with your hand. There are several good YouTube videos showing how to troubleshoot Xmas lights.

Works great

Decent Tester for Light DIY Use, but Not for Professionals The Neoteck Non-Contact AC Voltage Tester Pen is a solid entry-level tool for quick electrical checks, but it’s not without quirks. It reliably detects standard 120V and 240V lines and gives clear feedback through both light and sound. The built-in LED flashlight is handy for working in dark corners, and the fact that it runs on AAA batteries (instead of button cells) is a big plus for convenience and longevity. That said, it’s not the most sensitive unit I’ve used. It sometimes struggles to pick up lower voltages or hidden wires that higher-end testers (like Klein or GB) detect easily. The alert light pulses rather than staying solid, which can make subtle readings harder to interpret. The casing feels decent but slightly bulky, likely due to the battery design. For homeowners and DIYers doing basic outlet or wire checks, it’s perfectly fine and adds an extra layer of safety. Just don’t treat it as a precision instrument — confirm critical circuits with a multimeter before working on them. Bottom line: affordable, convenient, and good enough for everyday electrical safety checks, but not the tool you’d want to rely on for professional diagnostic work.

I received a similar voltage stick as this,CEF (UK)was the supplier, same circuitry etc, the unit is brilliant, with some knowledge, the unit shows on a bar or two ghost potential, mutual inductance etc, when on a live cable, like right next to the probe, it's red, for example on a three core flex, line, neutral and earth aka ground, the probe can be rotated around the circular flex and live can be located or neutral, even though it's very close to each other, used so many times it's simply practice to quickly test, so on a closely connected neutral and line it's child's play, The meter scale from yellow to red is really useful, as it's not a binary light up and sound OR not, relying very much on the tester to determine, but the accurate scale of (if memory serves) four yellow LEDs to two red leaves room for knowledge, intuition on experience, a quick rule of thumb, one or two yellow, ghost or residual or mutual/ inductance voltage, 3 or more yellow, neutral and finally one or two red, live, it varies one either way for type of circuit / equipment or situation, but the rule of thumb is like 95% spot on, I am a fluke,megger, metrowatt, kewtech, etc guy, but this voltage stick for a passive device is brilliant, the more you use it, then you just know how its nuances are, Invaluable and ability to create a higher resolution from the circuit dependent binary of live or not, sound and light up or not, just proves again, cost is no metric for quality or performance, Make sure if your meter is in reserve in a toolbox or in storage, REMOVE THE BATTERIES! batteries leak and knacker the meter, had a Klein pen voltage stick ruined by a leaking Duracell battery, fixed down to component level, but it's a non serviceable unit, so makes a mess getting into the gubbins,

It definitely beeps with power, but why do i beep? Science could tell me that i am feild generator, and it detects it, but i do not beep all the time? Is it fatal? No, luckily i am just low charge and it is expcted behaviour, it's just a sensetive tool, it's a bonus to me. Atleast i beep. Solid tool. Used to trace circuit breakers, and sanity checking cables, double check always with the multimeter!

⚡ Neoteck Tester di Tensione AC (Cercafase Senza Contatto) Caratteristica Dettaglio e Funzione Tipo di Strumento Cercafase Senza Contatto. Utilizza la tecnologia ad induzione per rilevare il campo elettrico AC (corrente alternata) che circonda un conduttore sotto tensione. Vantaggio Principale Sicurezza: Non è necessario toccare il conduttore, riducendo drasticamente il rischio di scosse elettriche. Sensibilità e Gamma 12V-1000V AC e 48V-1000V AC. La presenza di due range di sensibilità è un grande vantaggio: 48V-1000V: La modalità standard per la tensione domestica/industriale. 12V-1000V: La modalità ad alta sensibilità, utile per rilevare cavi nascosti in profondità, tensioni molto basse (es. 12V, 24V) o per distinguere tra fase e neutro. Display Display LCD. Fornisce un'indicazione visiva aggiuntiva (spesso una barra o un valore) sull'intensità del segnale o sulla modalità di sensibilità selezionata. Allarme Allarme Sonoro e Luminoso. Se viene rilevata la tensione, lo strumento emette un segnale acustico e un segnale luminoso (di solito rosso), con frequenza che aumenta all'aumentare dell'intensità del campo (ovvero, avvicinandosi al conduttore). Funzioni Aggiuntive Torcia LED. Molto utile per lavorare in quadri elettrici o scatole di derivazione in ambienti scarsamente illuminati. Design Penna Rilevatore di Corrente. Il formato a penna lo rende portatile e facile da trasportare nella tasca o nella cintura degli attrezzi. ✅ Utilizzo Principale Questo cercafase è essenziale per: Verificare la Tensione: Prima di lavorare su qualsiasi impianto (es. cambiare una presa o una lampada). Identificare i Cavi Sotto Tensione (Fase): Permette di distinguere quale cavo è la fase e quale è il neutro in una scatola di giunzione (la fase farà suonare l'allarme, il neutro no). Individuare Interruzioni: Muovendo la penna lungo un cavo, è possibile localizzare il punto esatto in cui un cavo interrotto perde la tensione. In sintesi: Il Neoteck è un tester di tensione senza contatto completo e versatile grazie alla doppia sensibilità, al display LCD e alla torcia integrata. È uno strumento di sicurezza fondamentale per chiunque operi con l'elettricità.
