NF-859GK Network Cable Tester with IP Tester and VFL Function

The NF-859GK Network Cable Tester is a versatile and upgraded multifunctional tool designed for professionals and enthusiasts alike. This device not only tests network cables but also includes an IP scanning function, making it an essential addition to your toolkit. With its ability to perform POE tests and connectivity checks, this tester is perfect for diagnosing and maintaining local area networks (LANs) that utilize the TCP/IP protocol.

One of the standout features of the NF-859GK is its powerful PING functionality. This allows users to authenticate connections and check the integrity of transmitted and received data. By measuring round-trip time, the device provides valuable insights into network traffic load and can even supply IP addresses, ensuring that you have all the information you need at your fingertips.

The dual-head VFL function is another impressive aspect of this handheld device. The upgraded receiver comes equipped with a red pen function, allowing for easy identification of cable faults. This feature, combined with the ability to connect with various transmitters, makes the NF-859GK a highly adaptable tool for any networking task.

When it comes to POE detection, the NF-859GK excels. It efficiently identifies PoE devices and can detect crossover modes, including unknown, end-span, mid-span, and 8-core power supply. The comprehensive detection capabilities include both non-standard and IEEE 802.3AF/IEEE 802.3AT standards, ensuring that you can work with a wide range of devices.

Additionally, the cable length measurement feature is a game changer. The NF-859GK can accurately measure cable lengths ranging from 8.2ft to 656ft (2.5m to 200m), providing real-time data and scanning for cable fault distances. This is particularly useful for professionals who need precise measurements for installations or troubleshooting.

As an Ethernet cable speed tester, the NF-859GK quickly evaluates network rate problems. It conducts PING tests from multiple locations to measure server and website responsiveness, allowing users to ensure cable integrity and continuity by identifying any breaks, openings, or shorts along the cable length.

The port flashing feature is another valuable addition. The indicator light on the connection port flashes to help accurately locate the cable, displaying important port information such as operating speed, duplex mode, and negotiation settings. This makes it easy to pinpoint lines and ports, enhancing your efficiency during network setups.

Finally, the NF-859GK is equipped with an LED light, making it easy to locate target cables even in dark environments. This feature is particularly useful for engineering cabling and network maintenance tasks. Whether you're a professional or a DIY enthusiast, the NF-859GK Network Cable Tester is a perfect gift for anyone looking to enhance their networking capabilities.
