Sonus GA216I Class 2 Integrating Sound Level Meter
Castle / GA216I
Sonus GA216I Class 2 Integrating Sound Level Meter
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 a combined sound and dosemeter, the range of systems covers a wide diversity of applications. The Castle Sonus GA216i is a feature packed instrument, fully compliant with IEC 61672:2013 Class 2. This meter gives simultaneous Leq and peak measurements for assessments to the Control of Noise at Work Regulations 2005. It has a high-specification measurement microphone and is cased in tough, crack resistant ABS plastic. It has a high-specification measurement microphone and is cased in tough, crack resistant ABS plastic.
Features of the GA216i:
Integrated equivalent level (Leq) measurement
Personal Sound Exposure Level (LEpd)
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
Elapsed time (running time hrs, min, sec)
Single Event Sound Exposure Level (LAE)
Overload and Under-range indication
Battery condition (Life approx. 12 hours)
Operation: Using your Castle Sound Meter couldn't be simpler. Operate your new Sound Level Meter by pressing the cleverly designed keys to navigate around the meters many features and capabilities. Intuitively developed, it will seem like you've been using one for years.
