The Narda Broadband Field Meter NBM-520 is a very compact hand held device for measuring electric and magnetic fields. The simplest possible operation with just four buttons. The field strengths are captured with flat frequency response probes or probes with shaped frequency response, allowing the measurement values to be assessed against an environmental or occupational safety standard. The calibration factors for each probe are stored in the probe itself and are read out and taken into account automatically by the measuring set.
The Narda NBM-520 provides virtually everyone concerned with this subject with an instrument for measuring non-ionizing radiation with utmost accuracy within the frequency range from 100 kHz to 60 GHz (depending on the probe used). The instrument features very simple operation, a handy design in a robust casing, long battery life, and high measurement accuracy.
Probes for various measurement applications are connected to the Narda NBM-520 basic unit. Flat frequency response probes are available, as well as so-called shaped probes that evaluate the field according to a specific human safety standard. These probes are calibrated separately from the measuring instrument, and include a non-volatile memory containing the probe parameters and calibration data. They can therefore be used with any instrument in the NBM-500 family without any loss in calibration accuracy.
The PC software supplied with the instrument allows you to remote control the Narda NBM-520 and to configure the instrument settings.
