Narda NBM-550 Broadband Field Meter
The Narda NBM-550 Broadband Field Meter stands out in the NBM-500 device family, designed for the precise measurement of nonionizing radiation. This robust instrument is ideal for professionals needing accurate evaluations of electric and magnetic fields across a wide frequency spectrum—from a mere few Hz, typical of industrial applications, to long wave and microwave radiation.
Equipped with advanced probes that deliver flat frequency response and human safety standard evaluations, the NBM-550 ensures comprehensive field strength assessments. Notable features include a probe that integrates built-in FFT analysis for spectral measurements in low-frequency ranges. Each probe is calibrated independently, incorporating a non-volatile memory that safeguards its calibration data, allowing compatibility across the NBM-500 family without compromising measurement integrity.
