Low Cost Noise Meter
Low Cost Noise Meter
Product Code: NM102
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.
