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 HIGHLIGHTS - 1/1 octave band included - 1/3 octave band optional - Accuracy class 1 - A, B, C & Z Frequency weighting - Fast, Slow, Pulse and Peak time weighting - Statistics function - Display of the sound curve as a graph - 3 measurement profiles adjustable - Low inherent noise - ICCP microphone 40 mV /PA - Alarm level adjustable SPECIFICATION Measuring range 22 ... 136 db(A) Accuracy Class 1 Frequency range 3 Hz ... 20 kHz Standards GB/T 3785.1-2010 GB/T 3785.2-2010 IEC 60651:1979 IEC 60804:2000 IEC 61672-1:2013 ANSI S1.4-1983 ANSI S1.43-1997 Frequency analysis 1/1 Octave band filter: 8 Hz ... 16 kHz 1/3 Octave band filter: 6.3 Hz ... 20 kHz Microphone 1/2" Microphone Class: 1 Sensitivity: 40 mV/PA Frequency range: 3 Hz ... 20 kHz Connection: TNC Power supply: ICCP Standard Data-logging interval 1 s ... 24 h (adjustable) Measuring functions LXY (SPL), LXeq, LXYSD, LXSEL, LXE, LXYmax, LXYmin, LXPeak, LXN X = Frequency weighting: A, B, C, Z Y = Time weighting: F, S, I N = Statistics in %: 1 ... 99 % Frequency weightings A, B, C, Z Time weightings Fast (F) 125ms, Slow (S) 1 sec, Impulse (I) 35 ms Inherent noise Microphone: 19 db(A), 25 db(C), 31 db(Z) Electronics: 13 db(A), 17 db(C), 24 db(Z) AD converter 24 Bit AD Sample rate Standard: 48 kHz LN Mode: 20 ms Measuring display Numerical Bar graph Graphical Display 160 x 160 pixel LCD with backlight Memory 4 GB Micro SD card Interface USB (Memory readable via software or directly as mass storage) RS-232 Voltage output AC 5V RMS DC 10 mV/db Alarm Adjustable Power supply 4 x 1.5 V AA Batteries 12 V / 1 A Power plug 5 V / 1 A USB Battery life Min. 10 h continuous use Dimensions 70 x 300 x 36 mm / 2.76 x 11.81 x 1.42" (W x H x D) Weight Approx. 620 g / 1.4 lbs incl. batteries
