Nor140 Sound Analyser

Nor140 Sound analyser

A precision hand held sound analyser designed for the most demanding users. A multi-tool for all acousticians, as it offers functions for almost all areas of application.

The Nor140 is packed into the smallest real time analyser featuring sound recording present on the market today.

The Nor140 sound level meter is very user-friendly, practical, reliable, robust, small, handy and light.
