New from Castle Group, the
pocket-sized Mirus sound meter has
a colour screen that rotates; full
octave and 1/3 octaves options; a
simple user interface; and
extendable memory.

The Mirus is available with
or without octave and 1/3
octave band frequency analysis
capability and will store a broad
range of sound parameters
across three measurement
profiles. Once a few basic
settings have been chosen, the
meter is always ready to go with just
one button. Results are stored on a
micro-SD card so there is no limit to
the amount of data that can be saved.

The meter is designed for use
across many applications, but is
particularly suited to Noise at Work
and Environmental assessments,
with parameters appropriate for
both. There is also a dosemeter
mode, which gives exposure
parameters such as Lepd and
DOSE%.

Measurements are then
transferred to PC software,
which can perform further
analysis and will display the
results in tabular and graphical
form.
