A precision hand held sound analyser designed for the most demanding users. With this analyser Norsonic set a new standard for sound level meters, covering the widest range of applications. The Nor140 is packed into the smallest real time analyser featuring sound recording present on the market today.

• Sound recording onto exchangeable SD card
• Level vs. Time with multispectrum function from 50ms resolution
• Parallel detection of SPL, L_eq, L_min, L_max, L_E, L_peak 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 - or 1/3-octave bands in the 0.4 Hz - 20 kHz range.
• 8.000 line FFT analysis with 1.46Hz line resolution
• 120 dB dynamic range giving an "one-range" instrument covering all levels from microphone noise floor at 15 dBA to maximum SPL at 137 dBA (140 dB peak)
• Pause/Continue function with 10 sec back erase function
• Manual or automatic storage of results with automatic measurement repeat and clock synchronization
• Building acoustics according to ISO 10052, ISO 140 & ISO 717 with on screen sound insulation indexes
• Dual channel building acoustic analysis using two Nor-140 controlled from CtrlBuild PC program hosted in the dual channel BA case Nor-518
• Noise generator
• Reverberation time calculations
• Support SweptSine measurement when used with CtrlBuild 1038/3 software
• Advanced Trigger functions
• Complies to all relevant IEC and ANSI Class 1 specifications
• Both USB 2.0 and RS232 high speed digital interface
• Wireless communication using Nor-520 Bluetooth transceiver
• RPM input
• High resolution backlit display
• ICP power for direct connection of vibration sensors
• Built-in random incidence correction and wind screen correction

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