PoE Detector & PoE Tester (Gen2) Tool Kit - Detect Power on The Network Cable + Test Power Over Ethernet to Determine Voltage, Current and Power Consumption on Network Cable, No Battery Needed

  • Both a must-have for any tech's tool box, this bundle will speed up your installs and eliminate guesswork. Our PoE Detector quickly detects the power supply on the network line and identifies PoE type. The PoE Tester measures power consumption from DC power supplies and activates any port on an AF/AT PoE switch..
  • The detector allows you to test the line prior to installing to instantly detect power. Use to safely install cameras, wifi access points, tablets, IP phones and more without damaging your device. The tester is a powerful tool for diagnosing PoE problems and easily observing loss in the Ethernet cable..
  • Enjoy infinite usage with no need for charging or replacing batteries. Both our PoE detector and PoE Tester draw power from the network line when in use, making them completely self-sufficient..
  • Small and ergonomic, both devices can fit snugly between two fingers so that they can be held while on a ladder or in a tight space during use. Toss them into your pocket or toolbox when you're finished..
  • The PoE Detector includes a chart located on the back of the device that is quick and easy to read. The bright LED indicators allow you to easily detect IEEE 802.3af, IEEE 802.3at, 24 Volt Passive and Reverse Polarity Mode B for Cambium and Canopy. The P....
