    Flexible 3-Phase Current Probe 30/300/3000A AC RMS

  • Flexible coils allow access to hard to reach cables and bus bars.
  • High bandwidth, low noise, low phase difference/Hz.
  • Although not powered from the scope, the battery lasts 2000 hours.

    The TA325 current probe uses the Rogowski coil principle to measure 3-phase AC currents up to 3000A, without suffering from saturation. This probe has flexible sensor coils, enabling you to measure currents on conductors that clamp-type curent probes just can't get to, while the long battery life means you can leave it conected for longer-term measurements.

    The probe is fitted with  BNC connectors, so you will need to use three TA271 single-ended  D9-BNC adaptors to connect it to the PicoScope 4444. The probe is not powered or sensed by PicoScope 4444 and can also be used with other oscilloscopes which have BNC inputs.

    The TA325 is a switched-range 30/300/3000A AC RMS probe with 10Hz to 20kHz bandwidth, rated to 1000V CAT III on uninsulated conductors. Suitable for measuring 3-phase AC current, it has three sensor coils and scope connection leads, colour-coded to match channels A, B and C in the PicoScope software. Typical battery life is 2000 hours.

    The TA325 probe is supplied without the depicted PicoScope 4444 and without the TA271 adaptors.
