New noise meter

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.
