Castle Sonus i, Class 1 Leq Sound Level Meter

The SONUS i (GA116i) is a Class 1 sound level meter and is designed for industrial safety officers, safety managers and engineers, for compliance with the Control of Noise at Work regulations 2005. It is fully compliant with European and International standards. The SONUS i will provide all necessary sound measurement information for completing noise at work risk assessments.

Simultaneous measurement of Lp, Leq, Lmax, Cpeak, Lep,d, LAE, Dose, Dose / Hour, Pa2H
'A' and 'C' frequency weighting (toggle)
'Slow' and 'Fast' Time constants (toggle)
Housed in tough, crack-resistant ABS plastic

The simultaneous measurement of LAeq and LCPeak makes the SONUS I ideal for measurements to The Control of Noise at Work Regulations 2005, which requires both these measurements. The SONUS i can also measure the 'C' weighted Leq values, which can be used for hearing protection assessments to the regulations.
