This Sound Level Meter or datalogger has bigger 30-130dB
range with built-in mic, 94dB at 1kHz
(sinusoidal) calibration signal and offers 4 measurement
parameters Lp, Leq, Lmax and LN.
Aside from the meter's 30 memory groups it is also
capable to transfer data from meter to computer directly
complete with real time and date stamp via RS-232C software.
It has the approval European Directives for health and safety
required standards and comply with IEC 651 Type 2,
and ANSI 1.4 Type 2.
