Class 1 Sound Analyzer
Model S660 is a Class 1 Integrating Sound Level Meter. This superior Class 1 Sound Meter offers a wider frequency range and a tighter tolerance over a Class 2 unit. This integrating meter sums the frequency-weighted noise to give sound exposure levels. Designed specifically for measuring environmental, occupational and product noise. Model S660 meets the current International standard for sound level meter performance IEC 61672-1:2002 Class 1. This standard directs the inclusion of an A-frequency-weighting filter and frequency weightings of C and Z (zero) frequency weightings.
