ETS-Lindgren’s HI-4433-MSE Electric Field Probe measures electric field strength and provides X, Y and Z as well as total field values. Data from each axis can be viewed individually or summed.

The RF field probe is fiber optically coupled to the readout or PC interface to eliminate the possibility of cable interference.
For additional frequencies and data ranges, ETS-Lindgren’s HI-4433 Series of RF Field Probes are battery-operated and designed for use in making RF exposure measurements.​​​
