This is a measuring device from Fluke, nothing more to say. It is an essential tester for network professionals. Ideal for coloring and identifying cable runs, qualifying and validating capabilities (10, 100, 1000, etc.) of cable runs, and troubleshooting crossed and loose cables. The CIQ-KIT includes everything you need to check up to 8 starts simultaneously with the included remote IDs, find cables with IntelliTone toner and run a range of other network tests. However, it does not come in the bag pictured but in a nice, secure carry case.
