  • Optical Fiber Meter - Checks fiber faults by emitting red lasers and tests optical power and attenuation value of light.

  • Wire Map - Tests the faults of short circuits, open circuits, and cross in a LAN network.

  • Anti-jamming Receiver - You can quickly and accurately locate a target wire in a bunch of wires with the receiver's anti-jamming probes, NCV, and adjustable sensitivity. For dim work environments, LED lights are ideal.

  • Port Flash - Determine the corresponding connection port by observing the same blink frequency on the switch/router port where the target cable is connected.

  • Length Test - Measures the length of CAT5 / CAT6 cables up to 200m, it can be measured in meters, yards, or feet.

  • PoE Test - It can test the information of a standard PoE device, such as PoE voltage, power supply polarity, power supply mode, and also the type of PSE.

  • HD Screen - As compared to previous models, the NF-8508 has a better high-definition screen with visual icons, which makes it easier to observe the detailed parameters of different modes, such as cont, scan, port flash, length, VFL, OPM .etc

  • QC Test - Tests the quality of the crimping of crystal heads.

  • Battery life is longer - Customize backlight off time and auto shutdown time, and charge the built-in lithium battery with a universal type-C cable.

  • What' s In The Box - Emitter *1, Receiver * 1, RJ11 cable adaptor *1, RJ45 cable adaptor *1, Alligator clip * 1, Eaphone *1, Type-c Cable *1, User manual *1

Great tester

I'm very pleased with your device, I haven't had chance to test for long period, but with the time and tests I deed, was good enough for me.
