Compact AC current clamp — 20 mm jaw, high precision, wide range Key features Jaw diameter: Φ20 mm — compact clamp opening fits single conductors and small cable bundles up to 20 mm. Measurement range: AC 0.1 mA to 200 A — covers very low leakage/measurement currents up to heavy loads. Resolution: AC 0.1 mA — detects small changes in AC current for diagnostic and monitoring work. Accuracy: 0.2% — high-precision measurements suitable for professional troubleshooting and verification. Why you need this product Safe, non-invasive AC current measurement: clamp over the conductor without disconnecting circuits, reducing downtime and risk. One sensor for many tasks: the wide range from 0.1 mA to 200 A removes the need to swap tools between low-current electronics and high-current power checks. Reliable, repeatable results: 0.2% accuracy and 0.1 mA resolution provide confidence when documenting measurements or comparing readings over time. Performance and compatibility Designed specifically for AC current measurement across a broad dynamic range. Compact Φ20 mm jaw works with most single conductors and small multicore cables; ideal where space is limited. Lightweight, portable form factor for field service, bench work, or permanent monitoring setups. Practical use scenarios Electrical troubleshooting in commercial equipment: quickly verify motor start currents, identify overloads, and detect intermittent AC faults without interrupting service. Power quality and maintenance checks in panels: measure branch currents and verify balance between phases, or monitor load changes over time. Sensitive electronics and leakage detection: detect small AC leakage or standby currents down to 0.1 mA for appliance testing and laboratory diagnostics. What it solves Eliminates the need to open circuits for current measurement. Reduces tool changes with a single, wide-range clamp. Improves diagnosis speed and measurement confidence with high resolution and accuracy.
