• AYA Instruments Current Probe
• Hard carry case

The P75.3C clamp-type current probe offers accurate, non-intrusive AC/DC current measurement for electrical testing applications. Compatible with multimeters, recorders, and power analysers, it leverages Hall effect technology to measure currents from 10 A to 7500 A across a wide frequency range up to 1 kHz. Ideal for use in industrial and laboratory environments, it delivers precise performance with low phase error and excellent conductor positioning sensitivity.
