Sound Analyser NOR 140
A precision hand held sound level meter designed for the most demanding users.
The Nor140 is packed into the smallest real time analyser featuring sound recording present on the market today.
- Our most affordable Sound Level meter with FFT.
- Sound recording onto exchangeable SD card.
- Level vs. Time with multispectrum function from 25 ms resolution.
- Parallel detection of SPL, Leq, Lmin, Lmax, LE, Lpeak and 8 statistical values.
- Measurement of A-weighted levels simultaneously with either C- or Z-weighted levels.
- Parallel F, S or I time constants.
- Frequency analysis with 1/1-octave or 1/3-octave bands in the 0.4 Hz – 20 kHz range
- 8000 line FFT analysis with 1.46Hz line resolution.
- 120 dB dynamic range giving a “one-range” instrument covering all levels from microphone noise floor at 15 dBA to maximum SPL at 137 dBA (140dB peak).
- Pause/Continue function with 10 sec back erase function.
- Manual or automatic storage of results with automatic measurement repeat and clock synchronization.
- Full support for all relevant Building acoustics standards such as ISO 10052, ISO 12283, ISO 140, ISO 717, ASTM E336 and E1007 with on screen sound insulation indexes.
- Built in Noise generator.
