  • Specifications given based on on-body use
  • Field replaceable sensor modules
  • Full color LCD display
  • Multi-color alarm
  • USB port for data and charging
  • Interchangeable lanyard or belt clip
  • Comprehensive software included
  • Can be deployed with NBM-580 for collecting readings from multiple Nardalert meters and probes

Properties: The Nardalert S3 features field replaceable sensors, a large color display and comprehensive user-friendly software. The unit touts a brand-new mechanical design with removable sensors that provides for rapid field support and unlimited upgradeability for users. This new model's top-mounted color LCD simplifies operation and improves the user's situational awareness.

Narda engineers even included a protective silicon skin for field use, and interchangeable belt or lanyard clips.


What the experts say about the Nardalert S3.

1. YouTube Video - This video summarizes comparison tests conducted on Narda monitors and other so called similar devices in the market. The tests were performed, on and off the body, using real world antennas. The video clearly illustrates the outstanding performance of the Narda monitors and the questionable results obtained from the competitive monitors.

2. Tests performed by the UK's prestigious NPL (National Physical Laboratory) - This report documents the ability of the NS3 to provide isotropic detection at frequencies less than 100 MHz, when worn on the body. Our engineers believe no other monitor achieved satisfactory results. Please click here to view test report.

3. ELF/VLF immunity tests by the U.S. Department of Energy - Bonneville Power Authority. These tests were performed to determine if the Nardalert S3 would false alarm in the presence of a strong ELF field (100 kV/m) and/or fail to correctly detect an RF field. Please click here to view the report.
