   The Narda EMR-30 Radiation Meters are compact, battery powered, and easy to operate. The remote sensor is a nondirectional measurement probe. The built-in optical interface allows each of the three axes to be evaluated separately and also allows complete remote-control of all instrument functions.

Long operating time from batteries

   The EMR-30 is equipped with rechargeable batteries as standard. These can be recharged while still fitted in the instrument, and give about 8 hours operating time. If dry batteries are used, up to 30 hours operating time can be expected.

Features

  • Frequency range 100 kHz to 3 GHz
  • Measurement range 0.6 bis 800 V/m, 0.0001 to 170 mW/m2
  • Special features Automatic zero alignment, averaging (time), averaging (spatial) and data memory
  • Display units mW/cm2, W/m2, V/m, A/m

Applications

   Precision measurement of electric field strength for personal safety at work where high radiation levels are present, and for applications involving electromagnetic compatibility (EMC), such as:

  • Service work on transmitting equipment
  • Working with plastic welding machines
  • Operating diathermy equipment and other medical instruments producing short-wave radiation
  • Drying equipment in the tanning and timber industries
  • Field strength measurements in TEM cells and absorber chambers

Fields of application

   The frequency spectrum is normally divided into two areas:

1: Low frequencies up to about 30 kHz.

   This region includes some railway system overhead power supplies running at 162/3 Hz, domestic a.c. power at 50/60 Hz and extends up to VDU workstations at 30 kHz (see EFA data sheets).

2: High frequencies above 30 kHz.

   Typical frequencies encountered here are FM radio (88 to 108 MHz), television signals (40 to 900 MHz), mobile radio (400 to 1800 MHz) and satellite communications (up to 18 GHz). Other frequencies which are often used in industry and medicine are 27, 433 and 2450 MHz. Knowledge of the frequency is important when monitoring limit values for electromagnetic fields because these limit values depend on the frequency.
