PCE-430 Octave: Class 1 Octave Band Analyzer with 1/3 octave band filter
DESCRIPTION
PCE-430 is a class 1 sound level
meter that meets IEC 60651:1979, IEC 60804:2000, IEC 61672-1:2013, ANSI
S1.4-1983 and ANSI S1.43-1997 requirements. This portable high-accuracy sound
level meter has a large easy-to-read illuminated LCD screen that displays the
sound pressure level (SPL) numerically and graphically in real time. Thanks to
octave band filtering, even the slightest difference in frequency is detected.
The handheld meter also functions
as a data logger, recording measurements at an adjustable interval from 1 s ...
24 h and storing the recorded measurement data to a micro SD card memory. The
SD card can be removed from the meter and inserted into the SD card reader of a
PC
