A Popular Science

Extended Description

Innovative and durable noise detection, the NI-100 noise indicator alerts you when noises in an area reach potentially hazardous levels. The noise indicator?s small size and lightweight design make it ideal for workers in a variety of industries. With a rechargeable battery that operates for up to 200 hours between charges, it?s an economical investment in your hearing conservation program.

The NI-100 can be used as an effective training tool within a Hearing Conservation Program (consult OSHA Standard 1910.95) to help ensure workers know when and where to wear hearing protection. Safety and health professionals can also use it as a mapping tool to determine where noise studies are necessary. In a variable noise environment, the 3M noise indicator can help train workers as to when noise levels become potentially hazardous and hearing protection may be required.
*The NRR may overestimate the hearing protection provided during typical use. 3M recommends reducing the NRR by 50% for estimating the amount of noise reduction provided.
3M™ Noise Indicator NI-100 is not Intrinsically Safe.
