Narda NBM-550

NARDA NBM-550

The Narda NBM-550 Broadband Field Meter is part of the NBM-500 device family. It makes extremely accurate measurements of nonionizing radiation. Equipped with probes for measuring electric and magnetic field strengths, it covers all frequencies from just a few Hz as found in industrial applications through to long wave and on up to microwave radiation. Flat frequency response probes ( €œflat probes "), as well as so-called shaped probes that evaluate the field strength on the basis of a human safety standard are available. A probe with built-in FFT analysis enables spectral measurements in the low frequency range. These probes are calibrated separately from the field meter, and include a non-volatile memory that contains the probe parameters and calibration data. They can therefore be used with any device in the NBM-500 family without losing any of the calibration accuracy.

The Narda NBM-550 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 th Narda NBM-550 include:

• Non-directional measurement using isotropic probes for applications in the frequency range 1 Hz to 90 GHz
• Large, graphic display for easy-to-read results
• Intelligent probe interface with automatic detection of probe parameters for simple operation
• Memory for up to 5000 measurement results
• Automatic storage of position data with GPS interface and plug-in GPS receiver (accessory)
• Voice recording for comments
• Optional Probe for spectral measurements and Weighted Peak from 1 Hz to 400 kHz

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)
