Castle 'SONUS' GA116I Combined Integrating Sound Level Meter and Dosemeter

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.

The Castle SONUS GA116I is a feature packed instrument that is fully compliant with IEC 61672-1:2002 Class 1, IEC 60651: 1979 Type 1, IEC 60804: 2001 Type 1 and IEC61252: 1993. This meter gives simultaneous Leq (rms. average) personal exposure (LEpd) and peak measurement for assessments to the Noise at Work Regulations 1989. It has a high-specification, Class 1 measurement microphone and is cased in tough, crack resistant ABS plastic.

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 reports.

There are a number of system packages available to suit many applications from simple tasks such as alarm monitoring, to a fully weatherproof system for long-term environmental monitoring, there are also dedicated packages for Noise at Work requirements.

POCKET POWER

Feature-Packed

Designed for Industrial Safety Officers and Safety Managers for compliance with the Health and Safety at Work Act; Noise at Work regulation 1989. The Castle GA116I provide all the necessary information you need for completing Noise at Work risk assessments.

  • Integrated equivalent level (Leq) measurement
  • Personal Sound Exposure Level (LEpd)
  • Optional dosemeter plug-in microphone
  • Sound Pressure (Lp) to 0.1 dB resolution
  • 'A' and 'C' frequency weighting (toggle)
  • 'Slow' and 'Fast' Time weighting (toggle)
  • Simultaneous measurement of Lp, Lmax, and Cpeak
  • Lmax - maximum Lp hold (rms.)
  • Cpeak - maximum peak level
  • Pascal Squared Hours (Pa2h)
  • Elapsed time (running time hrs, min, sec)
  • Single Event Sound Exposure Level (LAE)
  • Overload and Under-range indication
  • Battery condition (Life approx. 12 hours)

A Tough Case for all Weathers...

The physical design and construction of the Castle GA116I casing is extremely tough and durable, made from a substantial thickness of ABS, crack resistant plastic, the GA116I will stand up to almost any industrial environment.

Simplicity and Power...

Using the meter could not be simpler. The simple operating system uses logical keys to immediately display the information you need. The power of this little wonder means that it can measure simultaneous 'A' weighted Leq, exposure as well as monitoring the Peak levels. By simply plugging in a different microphone, this meter becomes a personal sound dosemeter.

Future-Proof...

The built in software for this meter is designed to suit future upgrading for feature enhancements, legislative changes or instrument upgrades. Details are mailed to customers as soon as they become available. With the Castle Pocket meters, you will always be in step with the law and market requirements.
