Nor140 Precision Sound and Vibration Analyzer


A precision hand held sound analyser designed for the most demanding users. The Nor140 sets a new standard for sound level meters, covering the widest range of applications.

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

The Nor140 is more than a Sound Level Meter, it is a measurement platform used in Environmental Noise Monitoring Systems as well as a front end in Nor850 - Norsonic's Multi-channel Building Acoustic and Sound Power Analyzer.

Measuring Vibration Using the Norsonic Nor140

The Norsonic Nor140 sound level meter can be used to measure more than just sound in decibels.  Among other things, it can be used to measure vibration in linear engineering units.  These engineering units can be anything the user selects such as m, m/s, m/s2 or g’s.
