The EFA-200 and the EFA-300 are part of the range of portable and personal devices for measurement and protection against electromagnetic, radio frequency and microwave ration offered by Air-Met Scientific Pty Ltd.

These field analyzers are designed to measure magnetic and electric fields in the workplace and in public spaces and for professional users in the power industry, at municipal utilities, by insurers, and for health and safety professionals in industry.

The EFA-200 and the EFA-300 are capable of handling practically any measurement required in the low frequency range, simply and precisely. These field analyzers use an FFT computation in addition to measuring magnetic and electric fields. Thanks to an innovative STD mode further application areas are open with the measurement results for magnetic and electric field strength are displayed as a "Percent of Standard," regardless of the signal shape. This mode also enables fast and reliable measurement and evaluation of the typical fields where complex, non-sinusoidal signals are common, e.g., in industrial applications that use resistance welding.

Resistance welding issues surface in the traditional 50/60 Hz systems as well as in the newer medium-frequency switching units.

Some of the applications of the EFA-200 and the EFA-300 field analyzers include:

  • Evaluation of Field Exposure
  • Shaped Time Domain (STD)
  • Fast Fourier Transform
  • Large Capacity Data Storage
  • Remote Control
