NM102 Noise Meter |
Due to its auto-ranging feature and simple push-button operation,
this noise meter is extremely easy to use. Just switch it on and
it is measuring with the most common settings: "A" frequency
weighting and "Fast"
time response. At the push of a button you can change it to display
the
"C" weighted sound level or change to "Slow" time
response. The large display with back light make this meter ideal
for measuring noise levels where the natural light is poor.
Noise at Work Measurements
Please note that for measuring occupational noise to the European
Noise at Work regulations, you should usually use a Type 2 Integrating Sound
Level Meter rather than a simple non-integrating meter such as
the NM102. For more help please visit our Noise
at Work information page. For any noise monitoring application
it is always wise to check whether there are any regulations that
state the grade of meter that should be used and define the parameters
that the meter should measure.

Meter web site.

Noise Meter and Calibrator
If you need a Sound Level Calibrator then
the NM102 Noise Meter is available in a Noise Measurement
Kit, order code NM102-K, which includes the calibrator, wind
shield, hard carrying case and soft carrying case.
Please visit the Noise Meter with
Calibrator page for more information. |
