Pocket-sized

3M has added to its passive hearing
conservation range with the
introduction of a lightweight, clip-on
product that provides health and
safety managers with a quick and
simple guide to potential noise
hazard levels.
The new 3M Noise Indicator NI-
100EU offers easy, durable noise level
detection, helping identify areas
where hearing protection may need
to be worn. It uses an LED lighting
system, which flashes green when
exposed to ambient noise levels below
85db(A) and red for noise levels
above 85dB(A), when hearing protection
equipment must legally be worn.

Small and lightweight, the Noise
Indicator has a rechargeable battery
that operates for up to 200 hours
between charges, and an automatic
turn-off system.
