T0-220 current probes from Teledyne Test Tools.

The T0-220 current probes complete Teledyne Test Tools’ offer


  • Teledyne LeCroy announced the expansion of its Teledyne Test Tools (T3)-branded portfolio of test equipment with the launch of the T0-220 series Rogowski coil current probes.

Rogowski coil current probes are designed for measuring alternating current or high speed current pulses.

This range of T0-220 probes includes five models with measurement capacities up to 6,000 amperes.

The measurement is carried out without contact by simply encircling the current loop around the cable to be controlled.

The probes connect to the oscilloscope via a standard BNC connector. They can therefore be used with all oscilloscopes on the market.

These current probes, which are available from 1500€ (about $1,720), are supported by Teledyne LeCroy worldwide.
