EHP-200A Compact E and H Field Meter

Selective and Wideband Measurement of Magnetic and Electric Near and Far Fields in the RF Range.

Frequency selective measuring system for electric and magnetic fields. As well as for workplace safety applications in industry, the EHP-200A is also ideal for determining the near and far fields of broadcasting transmitters.
The EHP-200A can be used to demonstrate safety around large scale antenna arrays, check the actual transmitted power in the actual direction of radiation, test the function of the transmitting antennas, and determine the border between the near and far field regions.
