Castle / GA116I
Sonus GA116I Class 1 Integrating Sound Level Meter
The Castle SONUS GA116I is a feature packed instrument that is fully compliant with IEC 61672-1:2013 Class 1, and IEC61252: 1993. This meter gives simultaneous Leq (rms. average) personal exposure (LEpd) and peak measurement for assessments to the Control of Noise at Work Regulations 2005. It has a high-specification, Class 1 measurement microphone and is cased in tough, crack resistant ABS plastic.
For compliance with the Control of Noise at Work Regulations 2005, the Castle Sonus i provides you with everything you need to assess Noise in the workplace
