Features & Benefits

  • Locate The Target Cable Quickly - Two scanning modes, analog and digital, can be switched at any time, with an anti-jamming probe, adjustable sensitivity, tone generator, and LED light, so that the receiver can quickly and accurately locate the target cable in a wide variety of complex environments.
  • Ethernet Continuity Test - Analyze CAT5 CAT6 (STP & UTP) line faults, such as normal, open circuit, short circuit, and cross, and see the results instantly.
  • Measure Cable Length Accurately - Measure the network cable in the range of 2.5m-500m.
  • Port Blink Test - Identify the network port by the blinking port light on the Hub or Switch. Available to 10M/100M/1000M Hub/ switch.
  • PoE Testing - Identify which pins are providing power and detect how much voltage, and identify which type of PSE (AT/AF standard).
  • Work Safely - Non-Contact Voltage (NCV) tester detect AC voltage (70V-1000V) without disrupting the electrical system, providing you with maximum safety and convenience.
  • Rechargeable Battery- The network tester can be recharged using a USB-C cable, and the lithium battery provides long-lasting power.
  • Other Functions - Quality control of the crimping crystal.
  • Certification - Passes RoHS, FCC, and CE compliance testing, and Noyafa is certified to the ISO 9001 standard.
  • 100% Affordable - Manufactured in China and a lot cheaper than competitor products with similar quality. Like Fluke.
