AC/DC Current Probe 500A 12MHz

The Pintech PT-3125 is a high-precision current probe for oscilloscope measurement of AC and DC signals. It captures waveforms across a DC to 12MHz bandwidth with a ±2% accuracy rating. The probe clamps around conductors up to 20mm diameter using a standard BNC connector for wide instrument compatibility. It ships with adaptors, cables and a manual.

Suited for engineers measuring power circuits

This probe serves technicians who need to visualise current waveforms up to 500A peak on an oscilloscope. The 10mV/A output ratio simplifies signal scaling for rapid analysis. It is not suited for users requiring measurements beyond 170A rms continuous or below 100mA minimum threshold. Applications demanding higher bandwidth or multi-channel logging without additional hardware should look elsewhere.

12MHz bandwidth defines measurement capability

The DC to 12MHz bandwidth with a 30ns rise time determines the fastest transient edges this probe can resolve accurately. At ±2% accuracy, it meets general-purpose power and automotive diagnostic needs. The 100mA rms noise floor sets the practical limit for low-level signal clarity. Select this probe when your oscilloscope analysis requires this specific frequency response and current range.

Questions about this item

What comes in the box and do I need to buy a BNC cable separately?

The package includes the PT-3125 probe, adaptors, a BNC cable, a power cable, an adapter and a manual, so no separate BNC cable is required.

Should I choose the 500 A peak or the 250 A DC rating for my application?

The probe handles 500 A peak-to-peak AC and 250 A DC, with a 170 A rms continuous limit; select based on whether your signal is primarily AC or DC.

What does the 12 MHz bandwidth mean when I connect it to my oscilloscope?

It means the probe accurately captures current waveforms from DC up to 12 MHz with a 30 ns rise time, provided the oscilloscope bandwidth matches or exceeds that range.
