The Amprobe TL245A test leads are two silicone-insulated lead wires with two standard probe tips for connecting a compatible electrical test meter to a device in electrical testing applications. The 48″ lead wires have silicone insulation to protect hands from shock and heat. The silicone insulation resists melting in hot environments and becoming brittle in cold ones, and it maintains flexibility better than polyvinyl chloride (PVC) insulation. The standard probe tips are held against the conductor during testing. The lead wires can be used with testing devices that have universal 4 mm jacks.
