Even higher requirements for copper core. Contains 42 pure copper core wires; easily handles currents of 10A and avoids leakage problems. The nylon wire inside allows it to withstand thousands of bends without breaking or fraying. Safer, more durable silicone cable Constructed with flexible, double-layered, insulated PVC/PA material. The silicone used is non-toxic, environmentally friendly, and meets UL and RoSH standards. The use of high-quality materials ensures that the test leads are durable, flexible, and have properties such as frost resistance and heat tolerance. Premium Test Tip and Plug Pure nickel-plated copper test lead tips that do not break easily, have strong contact characteristics, and fast and stable measurement reaction times. And the kit protects it from dust and oxidation. An efficient and stable connection is thus ensured. Domestic and Industrial Application Thanks to CAT.II 1000V ratings, currents of 10A can be safely tested. Recommended for general measurements. 2mm 10A alligator clips for use with 20A measurement probes. Easy access to ICS, LEDs, SMDs, etc. Probe resistance: <0.13Ω (it cannot be tested with high-frequency AC signals). It is super sharp, can easily pass through the cable's bark. But do not force it against hard objects.
