Features: Applications: Used in electric circuit, battery-powered projects, electrical or laboratory electric testing work. They are useful for connecting components to wires. Function: Equipped with alligator clips at both ends of each test lead to securely ensure good conduction. The clips are soldered and stamping to the wires which offer low resistance and high sensitivity. Superior Material: The test line set is double insulated by silica gel, and the clip is made of nickel-plated steel and PVC insulator, which is durable, non-toxic, soft, antifreeze and heat resistant. .
