Sound level meter with A and C weightings and SLOW FAST response CLASS 2 according to IEC 61672. This meter has the additional feature of signal integration over a programmable interval with calculation of SPL (Sound Pressure Level) and Leq (Equivalent continuous noise level). The sound logger is part of the Lutron SD series with logging at intervals from 1 second to 3600 seconds and data saved to SD card in EXCEL format, so further analysis can be readily undertaken.
