3M™ Noise Indicator NI-100, Hearing Conservation 10/Case
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.
∙ Red Flashing LED indicates noise levels are above 85 dBA and hearing protection may be required.
∙ Green Flashing LED indicates noise levels are below 85 dBA and hearing protection may not be necessary.
*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 is Leading the Advancement of Hearing Conservation™. 3M™ Noise Indicator NI-100 is not Intrinsically Safe."
