Class 2 Data Logging Sound Level Meter with Certificate PCE-428, Datalogging Class 2 Sound Level Meter Class 2 Noise Level Meter Certificate Integrating Sound Meter Datalogging db Frequency Time Weighting: PCE-428 is a class 2 data logging 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. The sound level meter calculates the equivalent continuous sound level Leq (LXeq). - Measuring range: 25 ... 136 db(A) - LXY (SPL), Leq (LXeq), LXYSD, LXSEL, LXE, LXYmax, LXYmin, LXPeak, LXN - Frequency weighting: A, B, C and Z - Time weighting: Fast (125 ms), slow (1 sec) and impulse (35 ms), decay (1500 ms) - adjustable data-recording interval from 1 s ... 24 h - 1/1 octave band filter (optional 1/3 octave band filter upgrade) - Includes factory calibration certificate according to ISO 9001 PCE-428 Class 2 Data-Logging Sound Level Meter Portable high-accuracy decibel meter with 1/1 octave band filter (optional 1/3 octave band filter upgrade) / Includes factory calibration certificate according to ISO 9001 PCE-428 is a class 2 data-logging 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. Alternatively, the decibel meter can be connected directly to a PC via USB. The provided PC-compatible software allows for quick and easy data analysis. This device measures from 25 ... 136 db(A) at a frequency of 20 Hz ... 12.5 kHz. The meter features A, B, C and Z frequency weightings as well as fast, slow and impulse time weightings. The PCE-428 decibel meter is commonly used by professionals to ensure compliance with environmental noise regulations and workplace noise permissible exposure limits. - Accuracy class 2 - A, B, C and Z frequency weightings - Fast, slow and impulse time weightings - 1/1 octave band filter (optional 1/3 octave band filter upgrade - see drop-down menu above) - Adjustable data-recording interval from 1 s ... 24 h - Real-time numerical and graphical LCD display - Adjustable alarm - Includes factory calibration certificate according to ISO 9001 Measuring range 25 ... 136 db(A) Accuracy Class 2 Frequency range 20 Hz ... 12.5 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: 20 Hz ... 8 kHz 1/3 Octave band filter: 20 Hz ... 12.5 kHz Microphone 1/2" Microphone Class: 2 Sensitivity: 40 mV/PA Frequency range: 20 Hz ... 12.5 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: 20 db(A), 26 db(C), 31 db(Z) Electronics: 14 db(A), 19 db(C), 24 db(Z) AD converter 24 Bit 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 1 x PCE-428 class 2 data-logging sound level meter 1 x microphone 1 x wind noise suppressor (foam ball) 1 x USB cable 1 x PC software 1 x power supply 1 x factory calibration certificate according to ISO 9001 1 x user manual 1 x carrying case Note: This meter comes standard with a 1/1 octave band filter.
