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.
