SAFETY? Radio, TV, mobile phones, wireless services: Electromag- National and international authorities have fixed limit netic fields are the medium wherever such forms of values for such fields to prevent harmful effects. The communication are used. These fields affect everything field strengths allowed in the occupational environment around them including the people that are moving are usually higher than those for the general public,...

Legislators have laid the responsibility for ensuring safety upon the operators of transmitting equipment and the relevant authorities. These, in turn, can take advantage of the measurement services offered by organizations and independent providers. There is really only one way to make sure everything is safe: CHECK!

The Selective Radiation Meter and its measuring antennas are matched. Any antenna and any instrument in the range can be combined to form a handy unit. Plug and Play. W/cm The results can be shown in physical units, e.g. electric field strength in V/m, magnetic field strength in A/m, and power density in W/cm or directly as a percentage of the limit values, for example those specified by ICNIRP.

WHO? WHAT? Broadcasting, mobile telephony, industrial equipment: SPECTRUM ANALYSIS What proportion of the overall field is from which source? The answer is of interest to the relevant authori- ties and safety representatives as well as to the opera- tors themselves. There is often a need to know what field strength is emanating from which equipment, which channel or which radio cell.
