- Model Nor1520 - Advanced Noise Monitoring Terminal



The Norsonic EMT Nor1520 is a complete Environmental Terminal for measuring noise and environmental parameters. It is a modular system which can be configured to measure just a few noise rating parameters or expanded into an enhanced system that will measure multiple noise parameters such as a full 1/3 octave frequency spectra including statistical parameters plus environmental data such as wind, temperature etc. The system can also continuously record audio and video to simplify noise source identification. One or more Environmental Terminals can be connected to a host computer to form a complete multi-channel monitoring system controlled by NorMonit software.

  • Collects noise data continuously
  • Continuous sound and video recording
  • Support GPS and weather data
  • Operates as a self contained unit collecting data off line or as one measuring channel integrated into a multi channel noise monitoring system
  • Double skin aluminium cabinet for optimal working condition for the measuring instruments in hot and cold environments
  • Supports ADSL, Wifi , LAN, GPRS, UMTS, EDGE and more Fault tolerant. Stores data locally if connection with host computer is down/faulty. The system will automatically transfer all data when connection is re-established
  • EU pattern evaluated for legal metrology
  • The following measurements are logged; Leq, Lmax, Lmin, Ln, Lpeak and 1/1 or 1/3 octave multi spectra in addition to A, C or Z spectral weighting functions
  • Runs 12h on internal batteries if mains disappears
