Manufacturer: 3M Brand: 3M Model: NI-100

Designed to alert the user to hazardous noise levels, the Noise Indicator N1-100 provides real-time noise detection. The detector clips to clothing and alerts to unsafe noise levels with a LED light, signaling when hearing protection may be required. A Popular Science "Best of What's New" in 2011, Noise Indicator NI-100 is designed to alert users to hazardous noise levels. It clips to clothing and uses a LED light to offer real-time noise detection, signaling when hearing protection may be required. 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.

Features three-decibel ranges for greater precision: low (35.0 to 80.0 dB), medium (50.0 to 100.0 dB), and high (80.0 to 130.0 dB). Resolution is 0.1 dB and accuracy is ±2 dB. Unit provides weightings for both A (frequencies for 500 to 10 kilohertz) and C (frequencies from 30 to 10 kilohertz) to meet IEC 651 Type-2 standards. Response time may be set to fast (0.2 seconds) or slow (1.5 seconds). A handy memory data-hold function stores the highest reading achieved for later display. It fulfills OSHA requirements. Unit uses a 1/2" condenser microphone. A recorder jack permits capturing readings (AC and DC 10 mV/dB). Use the threaded tripod insert for long-term measurements. To assure accuracy an individually serial-numbered Traceable certificate is supplied to indicate traceability to standards provided by NIST (National Institute of Standards and Technology). Unit is supplied with 9-volt alkaline battery and carrying case. Measures 3" width by 10" height by 1" thick and weight is 9.5 ounces.
