Conserve your hearing: use this small device to alert you when noise levels around you exceed 85dB.
Using the 3M Noise indicator, you'll always know when you need to wear ear defenders to protect your hearing.
The Noise indicator has a rechargeable battery. It gives you 200 hours of peace of mind!
Once the 200 hours have expired, you can also buy a recharger cable - to connect via a USB port. See USB cable for sale elsewhere on this site.
It is discrete, neat and effective: it also has a light indicator to warn the user when the noise level is hazardous.
Charging: A mini-USB cable plugs into bottom port of device. A mini-USB cable 3M Noise Indicator USB Cable NI-CHG sold separately.
I'm a QHSE officer: this is the most effective gizmo I've come across: Once the noise monitor flashes, non of the workers can argue: its so clear that the noise level has been exceeded and that they need to be wearing ear plugs/ear defenders. Clever & tiny noise monitor - I always wear it now. Very much recommend it.
