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.
The Nor140 may be extended with a large selection of optional features, thereby allowing you to tailor the instrument to your specific requirements. Optional features may be ordered and installed at any time by just adding a new set of option codes.

Option 17 Audiometer calibration
Option 18 Extended measurement range with the normal microphone (150 dB peak) including self noise compensation
Option 19 Extended noise monitoring features such as repeatable read-out
Sound level meter IEC 61672-1, class 1, group X measuring exponential time-weighted levels, integrating-averaging levels and sound exposure levels. If 1/1 octave-band or 1/3 octave-band filters are installed, the instrument complies with IEC 61260 class 1. The instrument also complies with the previous standards IEC 60 651 type 1 and IEC 60804 type 1.
