Narda NBM-520

NARDA NBM-520

The Narda NBM-520 Broadband Field Meter is part of the NBM-500 family of test instruments. It measures non-ionizing radiation with utmost accuracy and incorporates all the major basic measurement modes. In contrast with the larger   a memory for measurement results has been deliberately left out of the NBM-520. The result is unbeatably easy operation using just 4 buttons, so referring to the operating manual is all but unnecessary.

Suitable measuring probes for electric and magnetic field strengths are available for the frequency range from 100 kHz up to 90 GHz. So-called shaped probes which have frequency responses that weight the results according to specific human safety standards are available in addition to flat probes with flat frequency responses. All probes are calibrated independently from the measuring instrument. They include a nonvolatile memory containing the probe parameters and calibration data, so they can be used with any instrument in the NBM-500 family.

The Narda NBM-520 Field Meter is used to make precision measurements to establish human safety, particularly in workplace environments where high electric or magnetic field strengths are likely to occur.

Key features of the Narda NBM-520 include:

• Non-directional measurement using isotropic probes for applications in the frequency range 100 kHz to 90 GHz
• Intelligent probe interface with automatic detection of probe parameters for simple operation
• Extra small and lightweight
• Unbeatably easy 4-button operation
• Auto zero ensures precision measurements

Applications suitable for the Narda NBM-520 include:

• Measuring field strengths to comply with general safety regulations, such as the EMF Directive 2013/35/EU
• Establishing safe zones
• Measuring field strengths in the industrial environment, such as plastics welding equipment, RF heating, tempering, and drying equipment
• Measuring and monitoring field strengths around broadcasting and radar equipment
• Measuring field strengths of cell phone transmitters and satellite communications systems to demonstrate compliance with human safety standard limit values
• Measurements for protecting users of diathermy equipment and other medical devices that generate high-frequency radiation
• Measuring field strength in TEM cells and absorber chambers to demonstrate electromagnetic compatibility (EMC)
