Designed to make measurements a simple process, the Narda Model NIM-513 combines an unprecedented ease of operation with powerful measurement capabilities.

It provides the industrial plant manager and safety professional with an accurate and inexpensive solution for proving compliance with regulations that cover exposure to RF radiation. The NIM-513 model provides a complete measurement system comprised of an extremely easy to operate meter and a probe that contains sensors to measure both the electric (E) and magnetic (H) field components of an electromagnetic wave.

There is no need to change probes to measure the electric and magnetic fields as the probe contains two sets of sensors that seperately measure each field. Simply press the E/H Field key combination to change the field that you want to measure.

The Narda Safety Test Solutions NIM-513 Industrial Radiation Field Meter is available at all Air-Met offices for sale only. 

The Narda NIM-513 Industrial Field Meter Features: 
 
  • Complete Measurement System with Dual Electric and Magnetic Field Probe for Frequencies up to 100 MHz
    There is no need to change the probes as the probe contains two sensors that seperately measure each field.
  • Covers Most Industrial Equipment
    Measures both the electric and the magnetic field components (E and H fields) for equipment operating below 300 MHz.  
  • No confusing scales. Simply read the digital display including the unit of measurement
  • No difficulty zeroing with the Auto Zero executed repetitvely every 15 minutes
  • Fast and Reliable Measurements
  • Extremely Easy to Use
  • Low Cost, Compact and Lightweight
