Precision current probe for oscilloscopes

The Pintech PT-325 is a high-precision AC/DC current probe designed for oscilloscope users who need to capture waveforms up to 25 MHz bandwidth. It handles 100 A peak-to-peak AC and 40 A DC or RMS, with a typical accuracy of 1% ±5 mV and a 0.1 V/A conversion ratio. The 5 mm jaw diameter suits most conductors, while the BNC connector ensures compatibility with any oscilloscope input.

Thermals noise and power draw

The probe maintains a low noise floor of 6 mA RMS and a fast 14 ns rise time for clean signal capture across the full DC-to-25 MHz range. Its compact 144 x 17 x 29 mm body weighs 450 g including the adapter, making it easy to position in tight test setups. A 1.48 m cable provides flexible reach without adding bulk, and the included grounding wire helps maintain measurement integrity.

Upgrade path and fit

This probe replaces lower-bandwidth or lower-current clamps when engineers need 25 MHz response and 100 A peak capability in a single handheld tool. The jump is worth it when existing probes cannot resolve fast transients or exceed 40 A RMS limits. Buyers who require higher current ranges or bandwidths beyond 25 MHz will need a different class of instrument.

Questions about this item

How do I connect the PT-325 to my oscilloscope and what step is often missed?

Plug the BNC cable into the oscilloscope input, clamp the 5 mm jaws around a single conductor, and power the adapter before measuring.

Which parts will need replacement after extended use?

The BNC cable, grounding wire, power cable and adapter are the consumable accessories that may wear out over time.

What limit appears first during continuous high-current measurement?

The 40 A rms maximum continuous rating is reached before the 100 A peak rating, so sustained loads above 40 A rms will exceed the probe's limit.
