NBM-550 is part of the NBM-500 instrument family. It delivers extremely accurate results for electromagnetic field strength measurements. NBM-550 handles applications from a few Hertz through to long wave and on up to high frequency microwave radiation using a selection of interchangeable probes for electric and magnetic fields.
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.

| Model Overview |
|
| Model | Description |
| NBM-520 | The particularly handy NBM520 straightaway indicates the field strength in V/m, A/m, mW/cm², or W/m² – or directly as a percentage of the permitted limit value if you are using a Shaped Probe.
You can remote control the device or pre-configure it from a PC via its optical interface
|
| NBM-550 | The NBM-550 conveniently offers additional on-site evaluation facilities as well as storage for up to 5,000 results so you can process them and document them later.
The device can be hand held or fixed to a tripod, and can be programmed for long term measurements or remote controlled from a PC.
