Standard-Compliant Measurement of Electric and Magnetic Fields

Narda Safety Test Solutions (Germany) presents two new meters for equipment that operates using industrial frequencies. The devices make standard-compliant measurements of electric and magnetic field strength to determine the degree of exposure to electromagnetic radiation and demonstrate adherence to human safety regulations.

The Narda Industrial Field Meters NIM-511 and NIM-513 are complete hand-held measuring systems consisting of a basic unit and a measuring probe equipped with electric and magnetic field sensors. They provide an inexpensive solution for the task of checking the compliance of industrial plant with regulations and limit values for electromagnetic radiation.

The NIM-511 sensors cover a frequency range from 300 kHz to 100 MHz and are balanced during calibration at the 13.56 MHz ISM frequency often used in semiconductor manufacturing, for example.

The NIM-513 sensors cover the range 10 MHz to 42 MHz and are balanced during calibration at the 27.12 MHz ISM frequency – the frequency most often used for heat welding equipment and induction ovens.

True to task, the NIM devices are compact, weigh just 600 grams, and are easy to use. Since the probes measure the electric and magnetic fields at the same time, there is no need to switch probes, saving a lot of time when making measurements. Automatic measurement range selection, auto-zeroing, clear operating mode display, and a digital result readout make for reliable results and practically eliminate mistakes in measurement.
