Current measuring clamp | 20A | 320 mV | BNC connector | non-invasive AC current measurement | ST08
Code: ESST082Current clamps are a compact and accurate solution for non-contact alternating current (AC) measurement, suitable for both professional and advanced home use. These clamps allow fast and safe current measurement without disconnecting wires or interrupting equipment operation, making them ideal for diagnostics, testing, and measurements in live electrical systems. Thanks to the standard 320 mV output signal and BNC connector, the clamps can be easily integrated with oscilloscopes, data loggers, energy analyzers, and other measuring instruments.
