INTEGRATING SOUND LEVEL METER
Model: SL-4035SD

OVERVIEW:
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.

KEY FEATURES:
◆ Programmable integrating time provides precise linearity over a wide range (100dB) and displays Leq and SPL measurements
◆ Leq, SEL, SPL, MAX-L, and MIN-L measurements
◆ Heavy duty & compact housing case

SPECs:
◆ Range 30 to 130dB resolution 0.1dB
◆ Frequency 31.5Hz – 8,000Hz
◆ Real time clock – data logged to SD card
◆ MAX, MIN, HOLD, PEAK HOLD
◆ Calibrate using external sound source eq. Lutron SC-942/SC-934

EACH UNIT INCLUDES WITH:
◆ Instruction manual
◆ Hard carrying case

OPTIONAL ACCESSORIES:
◆ 94 dB/114 dB Sound Calibrator, SC-942
◆ 94/104/114 dB Sound Calibrator, SC-934
◆ Sound wind shield ball, SB-01
◆ SD Card
◆ USB cable, USB-01
◆ RS232 cable, UPCB-02
◆ Data Acquisition software, SW-U801-WIN

Frequency Weighting Network

Characteristics of A & C.

A weighting :
The characteristic is simulated as “Human Ear Listing” response. Typical, if making the environmental sound level measurement, always select to A weighting.

C weighting :
The characteristic is near the “FLAT” response. Typical, it is suitable for checking the noise of machinery (Q.C. check) & knowing the sound pressure level of the tested equipment.

Peak hold

To keep the peak ( max. ) measurement
