Precision and safety you can rely on: Test leads rated CAT III for up to 1000 V and 10 A provide safe operation in industrial and building installations while preserving measurement accuracy. Low contact resistance (≤ 0.001 Ω) minimizes influence on readings for precise voltage, current and resistance checks. Robust construction for repeated use: Rugged PA (polyamide) housings and stainless steel needle probes resist wear and maintain secure contact in tight test points. Red and black 4 mm plugs and probes clearly mark polarity for error‑free connections. Universal 4 mm banana compatibility: Designed to accept standard 4 mm banana plugs, these leads deliver stable electrical contact with meters, power supplies and lab instruments for consistent performance across devices. Compact, lightweight and long‑lasting: The compact design makes storage and transport easy for technicians and hobbyists. Built for durability and extended service life in both bench and field environments. Typical applications Electrical diagnostics and maintenance: Safely measure voltages and currents in distribution panels, motor control circuits and building wiring up to CAT III, 1000 V. Electronic lab and test benches: Use for precise low‑resistance and continuity measurements, bench testing of components and instrument calibration where low contact resistance matters. Field service and equipment repair: Durable probes and 4 mm compatibility make these leads ideal for on‑site troubleshooting of industrial controls, power supplies and test instruments. Key specifications Safety rating: CAT III, up to 1000 V and 10 A Contact/resistance: ≤ 0.001 Ω Plug type: 4 mm banana plugs (red and black) Probe: Stainless steel needle Housing material: High‑quality PA (polyamide) What this means for you Safer work on higher‑energy circuits with a CAT III rating More accurate readings thanks to very low contact resistance Durable probes and clear polarity reduce mistakes and repeat visits Broad compatibility with standard 4 mm test equipment for flexible use in the lab, workshop or field
