| PEM CWT AC Current Probe | PEM LFR Dual-Range AC Current Probe | PEM CMC Common Mode Current Probe | PEM RCT AC Current Probe |
| The CWT is ideal for power electronics development work because it combines an easy to use thin, flexible, clip-around coil with an ability to accurately replicate fast switching current waveforms. | A dual range, clip-around, battery powered AC probe for general purpose ac power measurements. The LFR has a 10:1 switch selectable current ratio to give a wide dynamic range in a single probe. | A clip-around, current probe to measure high frequency common mode currents which flow from a variable speed motor drive to ground via the bearings in AC drive systems. | AC Rogowski Coils with a DIN Rail Mounted Integrator for permanent or semi-permanent installation on equipment. They are exceptionally simple to retrofit into existing plant. |
