Sound level meters having functions to indicate Equivalent continuous SPL (Leq), Single event sound exposure level (LE), Persentile SPL (Lx) are suitable to Environmental noise measurements. The RS-232C interface is equipped to communicate with external CPU for continuous measurements.
Features
●Optionally selectable 5 values for Persentile SPL (Lx).
●Measurement of Equivalent continuous SPL (Leq) is available.
Environmental noise measurements needed for industrial health control is possible.
●Wide range of fine Linearity throughout 100dB
●RS-232C function is equipped.
●Data storage up to15,000 is possible by Memory function.
●Large display with back light.
