Optimus Red - Noise at Work Sound Level Meter |
|
The
Optimus Range |
|
|
|
The Optimus Red sound level meter
is for measuring sound levels in factories and other
work environments in line with the UK and EU occupational
noise regulations.
- Noise at work surveys
- Meets EU regulations and
HSE guidelines
- Quick and easy to use
- Voice tag recording of comments*
- Single range 20 to 140 dB
- 12 year warranty
Let the meter take the strain -
The Optimus Red has been designed specifically
for noise at work measurements. Rather than being
a general purpose meter that leaves you trying to
select the correct measurement range and parameters,
the Optimus Red does it all for you, recording all
the measurements that you might need now and in the
future. Lower cost meters are available
(even within our range), but they will not usually
meet the IEC 61672 standard and will not be Integrating as
required for occupational noise measurement. They
will certainly not be so powerful or easy to use. |

Buying the Right Meter
The noise at work regulations state that you should
use at least a Class 2 Integrating Sound Level
Meter that provides you with measurements of LAeq and
LCPeak. The meter should be verified by a suitably equipped
laboratory when new and at least every two years. You
also need a Calibrator to
check the meter's function before making measurements.
Our Recommendation
For basic occupational noise measurements, we recommend the
standard Optimus Red Class 2 (order code CR162A) with Calibrator
(order code CR514). The extra bits (logging and octaves) can
be added at a later date if needed.
For more advanced use, or where the noise levels are particularly
high, we recommend Optimus Red Class 2 with with
logging and octaves (order code CR162C) with Calibrator. This
gives the ability to assess the level at the ear when wearing
different hearing protectors.
