  • The Building Acoustic mode is improved for the latest Standards as well as extended for Service Equipment measurements. The BA mode of version 4.x offers the following sub-modes:
    • Airborne survey grade testing in accordance with ISO 10052
    • Impact survey grade testing in accordance with ISO 10052
    • Airborne engineering grade testing in accordance with ISO 16283-1, BS-ISO 140-4 and ASTM E336
    • Impact engineering grade testing in accordance with ISO 16283-2, BS-ISO 140-7 and ASTM E1007
    • Airborne survey grade testing in accordance with French NF-ISO 10052
    • Impact survey grade testing in accordance with French NF-ISO 10052
    • Service Equipment survey grade testing in accordance with ISO 10052
    • Service Equipment engineering grade testing in accordance with ISO 16032
  • The Nor140 now measures the ‘Moving Leq’ value in normal mode. This feature contains two individual moving values over user-defined time-frames with toggle markers depending on preset threshold levels.
  • The STIPA optional measurement is improved to measure in accordance with the latest IEC 60268-16 version 3 Standard

The modular design of the Nor140 enables functional expansion to take place when you need it.
