ETS-Lindgren's HI-4433-CH Magnetic Field Probe measures magnetic 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 HI-4433-CH is fiber-optically coupled to the readout or PC interface, eliminating the possibility of cable interference. 
For additional frequencies and data ranges, ETS-Lindgren's HI-4433 Series of Broadband Radio Frequency (RF) Isotropic Field Probes are battery-operated and designed for use in making RF exposure measurements.
