This low cost noise meter has been designed for simple noise surveys and sound level checks. Despite its full range of features, it is very easy to use and the large backlit display helps when measuring in poor light conditions.
Due to its auto-ranging feature and simple push-button operation, this noise meter is extremely easy to use. Just switch it on and it is measuring with the most common settings: "A" frequency weighting and "Fast" time response. At the push of a button you can change it to display the "C" weighted sound level or change to "Slow" time response. The large display with back light make this meter ideal for measuring noise levels where the natural light is poor.

Noise at Work Measurements
Please note that for measuring occupational noise to the European Noise at Work regulations, you should usually use a Type 2 Integrating Sound Level Meter rather than a simple non-integrating meter such as the NM102. For more help please visit our Noise at Work information page. For any noise monitoring application it is always wise to check whether there are any regulations that state the grade of meter that should be used and define the parameters that the meter should measure.
If you need a Sound Level Calibrator then the NM102 Noise Meter is available in a Noise Measurement Kit, order code NM102-K, which includes the calibrator, wind shield, hard carrying case and soft carrying case.
Please visit the Noise Meter with Calibrator page for more information.
