Frequently Asked Questions

  • Can the Nor282 run on batteries?
    Yes, the Nor282 can operate on battery power for field measurements in locations without mains power, making it ideal for construction sites and remote locations across the GCC.
  • Is it powerful enough for ISO measurements?
    Yes, 100 W output is sufficient for most field building acoustics measurements per ISO 16283 when paired with efficient loudspeakers such as the Nor283 dodecahedron.
  • What is the difference between the Nor282 and Nor280?
    The Nor282 is the compact, portable option at 4 kg with battery operation and 100 W output. The Nor280 offers higher 200 W power, wider frequency response, remote control, and frequency shaping filters for more demanding laboratory and field applications.
