Features & Advantages

  • New Upgrade Sensor. Swiftly captures weak and high-speed signals, and respond faster than the old sensor detection.
  • Circuit Breaker Location - In the circuit, connect the GFCI tester to a power outlet, and the receiver can scan the panel to locate the correct breaker.
  • Electrical Outlet Test - With the GFCI Tester, you can detect the most common wiring problems in standard and GFCI receptacles. AC90V-120V 50/60Hz (suitable for North American grounded outlets)
  • AC Wire Tracing - Detect wires hidden under the wall, and it can help you identify the direction of the AC circuit quickly based on the sound intensity.
  • Network Cable Tracking - Plugging a network cable into the emitter and using the receiver to trace, will allow you to locate and identify its direction.

  • NCV Detection - The NCV detectors detect whether any device or location has power. It is suitable for non-contact voltage detection and testing.
  • Adjustable Search Sensitivity - With the receiver's sensitivity adjustable to up to six levels, you can easily detect wires buried deep in the ground or walls.
  • LED Lights - With LED lighting on the receiver, even in low lighting, you can get the job done.
  • What's in the Box -Transmitter *1, Receiver *1, Exclusive accessory cable *1, Multimeter adapter cable *1, C04 alligator clip *1, USB-C cable *1, User manual *1, Toolkit *1

Q: Is it normal for the transmitter to detect a slight current sound when the ear is close to the strong current function?
A: It is normal, this is the sound emitted when the transformer is boosted, and it does not affect itsstandard function.

Q: How is the transmitter wired?
A: The transmitter can use the three plugs and crocodile clip wires in the accessories, depending on the situation. The three plugs are connected to the red end transmitter marked with "+" at the end andthe black end transmitter marked with "-". The plug is inserted into the jack of the socket. The crocodile clip is also a red oneend launcher with “+" end, a black onelauncher has the "-" end, and the clip then clamps the zero and earth lines.

Q: How can the receiver find a strong current?
A: The receiver probe moves along the general direction of the wall or buried line and when the signal is received, it will emit a sound. The stronger the signal, the louder is the sound which helps to determine the approximate position of the cable after setting the sensitivity adjustment knob.

Fantastic product!

I'm particularly impressed by the GFCI Test feature, which underscores the significance of the receptacle's cable sequence.

Perfect tool with a little adjustement

It works perfectly in all his function, but for European market with 220 VAC, it needs an EU plug and a transformer 110-220 VAC with earth reference too.
It may also needs the correct wires connection live/neutral/earth.
This has been confirmed by Noyafa Assistance.


The brand has always had excellence in all its tools. Easy to use

Easy-to-Use Product for Checking Electrical Outlets

I have to say, this is a great product. It's very easy to use and has saved me many trips back and forth to the breaker box.


As expected, everything went smoothly. The plug-insert storage method was particularly appealing to me.

    Meet Noyafa's New Arrival - NF825

    NF-825 helps people accurately find the position and direction of the cables and electrical lines buried inside a wall or underground. Also, it can find the location of interruptions and short circuit in cables and electrical lines. NF-825 is suitable for a variety of tasks from installing outdoor wiring layout or house decoration wire layout to home appliance maintenance, wire maintenance, and more.

    Detect Hidden AC Wires In Sec

    NF-825 combines essential tools for wiring and maintenance. Plugged into a power supply, the transmitter will give you a clear indication of where power cords are inside a wall and/or in which direction they run.

    Locate Faults in Cables

    The NF-825 can find the location of interruptions and short circuits in cables and electrical lines.

    Socket Test

    You can test the cable connection status inside a socket by connecting transmitter 2 to a power outlet. GFCI Tester detects the most common wiring problems in standard and GFCI receptacles.

    Digital Circuit Breaker Positioning

    With NF-825 you can easily identify circuit breakers in electric circuits. All you need to do is to connect transmitter 2 to a power outlet in the particular circuit and the receiver will automatically locate the circuit breaker.

    Identify & Trace Network Cables

    NF-825 makes network cable search fast and effortless. You can locate and identify the direction of a RJ45 ethernet cable by plugging it into transmitter 1 and use the receiver for tracing.

    NCV Induction Pen

    NF-825 power pen detects whether any device or location has power. It is suitable for non-contact detection of voltage and testing. For example, to detect whether the newly installed socket is powered on.

    Adjustable Search Sensitivity

    With NF-825 you can adjust sensitivity of electrical search to locate electric wires which are other wise hard to find. If a wire is deep underground or inside a thick wall, you can set the search sensitivity on the receiver to six different levels. And you can adjust the sensitivity levels during the search to pinpoint its location.

    LED Lights

    To ensure good visibility in in low-light areas NF-825 receiver is illuminated with LED lights. They use low power and can last long which reduces their impact on the environment.
