The Castle SONUS range of pocket sized sound level meters
bring simplicity and power to the worlds of Noise at Work
and Environmental sound monitoring. From a basic sound
pressure meter to full data-logging, combined sound and dosemeter,
the range of systems covers a wide diversity of applications.
Top of the Castle Pocket Range of Sound Level Meters is the
SONUS L (GA116L & GA216L), a Noise at Work and Environmental
Sound Meter boasting a combined integrating sound level
meter and dosemeter with full data-logging capability. Simply
un-plug the sound meter microphone and plug-in the dosemeter
cable to convert to a full-function dosemeter. The
dual-measurement feature of the SONUS means two
versions of most parameters can be measured simultaneously.
This feature means you only ever need to
measure once to capture all the data you need!
Mobility of instrumentation is essential for effective
noise measurement. As the name indicates, the Castle
SONUS ‘Pocket Meters’ pack all the necessary features
into pocket sized proportions.
The data-logging instruments have a USB connection
and are compatible with the Castle dBdataPro software,
where data can be presented in the desired format and
copied and pasted into other applications, so you don’t
have to change the way you have always completed your
There are a number of system packages available to suit

All measured values can be saved to the internal
flash memory of the GA116L or GA216L for
subsequent output. The results can be viewed on
the instruments own display or downloaded to the
included dBdataPro noise analysis PC software via
a high speed USB connection.
Using the instruments could not be simpler. The
simple user interface can easily be scrolled and
selected to immediately display the information you
need. The keypad also has a dedicated dB Range
key, simply press and then select your required
The instruments also have 3 operating modes,

The measured noise is computed and stored as a
series of pre-chosen time intervals. The GA116L
and GA216L instruments will store up to
approximately 2100 intervals in either one or
Each instrument is supplied with a comprehensive
