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.<\/p>\n<p>The handheld meter also functions as a data logger, recording measurements at an adjustable interval from 1 s &#8230; 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.<\/p>\n<p>This device measures from 25 &#8230; 136 db(A) at a frequency of 20 Hz &#8230; 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.<\/p>\n<h3>Highlights<\/h3>\n<ul>\n<li>Accuracy class 2<\/li>\n<li>A, B, C and Z frequency weightings<\/li>\n<li>Fast, slow and impulse time weightings<\/li>\n<li>1\/1 octave band filter (optional 1\/3 octave band filter upgrade)<\/li>\n<li>Adjustable data-recording interval from 1 s &#8230; 24 h<\/li>\n<li>Real-time numerical and graphical LCD display<\/li>\n<li>Adjustable alarm<\/li>\n<\/ul>\n<h3>Technical specifications<\/h3>\n<ul>\n<li>Sound level \u2014 Measuring range: 25 &#8230; 136 dBA<\/li>\n<li>Sound level \u2014 Resolution: 0,1 dBA<\/li>\n<li>Sound level \u2014 Accuracy: Class 2<\/li>\n<li>General technical data: Analogue output DC 10 mV\/db, AC 5V RMS<\/li>\n<li>General technical data \u2014 Measuring functions: LXN, LXPeak, LXYmin, LXYmax, LXE, LXSEL, LXYSD, LXeq, LXY(SPL)<\/li>\n<li>General technical data \u2014 Measuring functions: (additional information)X = frequency weighting: A, B, C, Z;<\/li>\n<li>Y = time weighting: F, S, I;: N = statistics in %: 1 &#8230; 99 %<\/li>\n<li>Y = time weighting: F, S, I; \u2014 Frequency: analysis:<\/li>\n<li>Y = time weighting: F, S, I;: standard 1\/1 octave filter 20 Hz &#8230; 8 kHz<\/li>\n<li>Y = time weighting: F, S, I;: optional 1\/3 octave filter 20 Hz &#8230; 12.5 kHz<\/li>\n<li>Y = time weighting: F, S, I;: Connections 1\/2 inch microphone<\/li>\n<li>Y = time weighting: F, S, I;: Time weighting Pulse (35ms), slow (1 s), fast (125 ms), peak<\/li>\n<li>Y = time weighting: F, S, I; \u2014 Frequency: weighting A, B, C, Z<\/li>\n<li>Y = time weighting: F, S, I; \u2014 Frequency: 20 &#8230; 12500 Hz<\/li>\n<li>Y = time weighting: F, S, I; \u2014 Display type: LCD with backlight<\/li>\n<li>Y = time weighting: F, S, I; \u2014 Display refresh rate: 1 x per second<\/li>\n<li>Storage medium Micro SD card \u2014 Storage capacity: 4 GB<\/li>\n<li>Storage medium Micro SD card \u2014 Storage interval from: 0,1 s<\/li>\n<li>Storage medium Micro SD card \u2014 Storage interval to: 24 h<\/li>\n<li>Storage medium Micro SD card: Microphone type Class 2 measuring microphone<\/li>\n<li>Storage medium Micro SD card \u2014 Interface: RS232, Mini-USB<\/li>\n<li>Storage medium Micro SD card: Standard(s)GB\/T3785.2-2010, GB\/T 3785.1-2010, ANSI S1.4-1983, ANSI S1.43-1997, IEC 60804:2000, IEC 60651:1979, IEC 61672-1:2013<\/li>\n<li>Storage medium Micro SD card: Operating time 10 h<\/li>\n<li>Storage medium Micro SD card: Automatic power-off 30 min<\/li>\n<li>Storage medium Micro SD card: Tripod thread 1\/4 inch<\/li>\n<li>Storage medium Micro SD card: Sensitivity 40 mV\/PA<\/li>\n<li>Storage medium Micro SD card \u2014 Menu language: English, Spanish, German, Chinese, French, Indonesian, Portuguese<\/li>\n<li>Storage medium Micro SD card \u2014 Protection class (device): IP20<\/li>\n<li>Storage medium Micro SD card \u2014 Power supply 100 &#8230; 240V AC: 50\/60 Hz<\/li>\n<li>Storage medium Micro SD card: Netzteil 12V \/ 1 A<\/li>\n<li>Storage medium Micro SD card: Mini-USB 5V \/ 1 A<\/li>\n<li>Connector type Device-europlug \u2014 (Rechargeable) battery: 4 x 1,5 V AA battery , Alkali-manganese<\/li>\n<li>Connector type Device-europlug \u2014 Capacity: 3000 mAh<\/li>\n<li>Connector type Device-europlug: Performance 4,5 Wh<\/li>\n<li>Connector type Device-europlug \u2014 Operating conditions: -10 &#8230; 50 \u00b0C , 20 &#8230; 90 % RH<\/li>\n<li>Connector type Device-europlug \u2014 Storage conditions: -10 &#8230; 50 \u00b0C , 20 &#8230; 90 % RH<\/li>\n<li>Connector type Device-europlug \u2014 Dimensions: ( L x W x H )200 x 80 x 36 mm<\/li>\n<li>Connector type Device-europlug \u2014 Weight: 245 g<\/li>\n<\/ul>\n<h3>Delivery scope<\/h3>\n<ul>\n<li>1 x PCE-428 class 2 data-logging sound level meter<\/li>\n<li>1 x Microphone<\/li>\n<li>1 x Wind noise suppressor (foam ball)<\/li>\n<li>1 x USB cable<\/li>\n<li>1 x PC software is a free download<\/li>\n<li>1 x Power supply<\/li>\n<li>1 x User manual<\/li>\n<li>1 x Carrying case Note: This meter comes standard with a 1\/1 octave band filter.
