Features: Featuring 8 double 4mm safety banana plugs with nickel plated copper contacts (resistance <0.05Ω) and insulated sleeves, these test probes deliver secure electrical connection and precise signals transmission for professional measurements. Flexible silicone test leads with color coded PVC jackets (100cm length) secure heat resistance up to 10amp current, while multiple color option simplify circuit identification in complex testing setups. Ideal for electrical engineers, automotive technicians, and lab professional requiring stable tools for sensitive measurements in industrial or educational environments. Perfect for diagnosing automotive electronics, calibrating industrial equipment, or conducting physics experiments where strong , oxidation resistant test leads are critical. The twist resistant design with reinforced stress points withstands repeated bending, making these probes a long lasting solution for fieldwork, workshop repairs, and multimeter based troubleshooting.
