The TSI Quest NI-100 noise indicator lets you know when noises in an area reach potentially hazardous levels. It's small, light weight, and can operate up to 200 hours between battery charges. In addition to everyday exposure, the NI-100 can be used as a training tool, to help workers learn when and where they need hearing protection. It can also be used to pinpoint and identify areas that may require further noise studies.
