Measurement of electric potential difference V and electric field E with non-contact sensor has become easier with the E probe of INPHYNIX, including frequencies as low as 20 mHz.

The E probe allows easier demonstration of basic phenomena:

• electrification of insulating materials
• Evaluation of static electric field
• characterization in intensity and direction of E fields associated with electric power distribution by the 50Hz
• Quantitative and qualitative work of Gauss: using the probe E with a positioning XYZ stage and rotation axis, used around a conducting circular electrode plane (giant electrical condenser)
• Projection / dot product / gradient by measuring potential or electric field Ez between plates
• Measurement of ε0

The new EM powersupply unit coupled to the probe E facilitates implementation through its various outputs:

• Large bandwidth
• Low pass filter (100Hz)
• Notch (50Hz)
• High sensitivity demodulation synchronous
