This portable, high-accuracy sound level meter has a large easy-to-read light-up LCD screen that displays the sound pressure level (SPL) numerically \u0026amp; graphically in real time. Thanks to octave band filtering, even the slightest difference in frequency is detected.\u003cbr\u003e\u003cbr\u003eThis handheld sound 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. The card can be removed from the meter and inserted into 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.\u003cbr\u003e\u003cbr\u003eThis 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.\u003cbr\u003e\u003c\/p\u003e\n\u003ch5\u003e\n\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003cbr\u003e\n\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e Accuracy class 2\u003c\/li\u003e\n\u003cli\u003eA, B, C and Z frequency weightings\u003c\/li\u003e\n\u003cli\u003eFast, slow and impulse time weightings\u003c\/li\u003e\n\u003cli\u003e1\/1 octave band filter (optional 1\/3 octave band filter upgrade)\u003c\/li\u003e\n\u003cli\u003eAdjustable data-recording interval from 1 s ... 24 h\u003c\/li\u003e\n\u003cli\u003eReal-time numerical and graphical LCD display\u003c\/li\u003e\n\u003cli\u003eAdjustable alarm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003eMeasuring range: 25 - 136 db(A)\u003c\/li\u003e\n\u003cli\u003eAccuracy: Class 2\u003c\/li\u003e\n\u003cli\u003eFrequency range: 20 Hz - 12.5 kHz\u003c\/li\u003e\n\u003cli\u003eStandards:\u003c\/li\u003e\n\u003cli\u003eGB\/T 3785.1-2010\u003c\/li\u003e\n\u003cli\u003eGB\/T 3785.2-2010\u003c\/li\u003e\n\u003cli\u003eIEC 60651:1979\u003c\/li\u003e\n\u003cli\u003eIEC 60804:2000\u003c\/li\u003e\n\u003cli\u003eIEC 61672-1:2013\u003c\/li\u003e\n\u003cli\u003eANSI S1.4-1983\u003c\/li\u003e\n\u003cli\u003eANSI S1.43-1997.\u003c\/li\u003e\n\u003cli\u003eFrequency analysis:\n\u003cul\u003e\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003e\n\u003cstrong\u003eHighlights\u003c\/strong\u003e\u003cbr\u003e\n\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003eMeasures from 25 - 136 db(A) at a frequency of 20 Hz - 12.5 kHz\u003c\/li\u003e\n\u003cli\u003ePortable\u003c\/li\u003e\n\u003cli\u003eHigh-accuracy\u003c\/li\u003e\n\u003cli\u003e1\/1 octave band filter (optional 1\/3 octave band filter upgrade)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003eWhat our Experts Think\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eProfessional-Grade Sound Measurement:\u003c\/strong\u003e Class 2 accuracy makes it suitable for environmental, workplace, and industrial noise monitoring.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Precision Decibel Detection:\u003c\/strong\u003e Delivers reliable readings for sound level analysis in compliance testing and audits.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide Application Range:\u003c\/strong\u003e Ideal for construction sites, factories, HVAC systems, events, and environmental noise studies.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClear Digital Display:\u003c\/strong\u003e Easy-to-read interface helps users quickly interpret real-time sound levels and trends.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eData Logging Capability:\u003c\/strong\u003e Supports recording and analysis of noise data over time for reporting and compliance purposes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable \u0026amp; Field-Ready Design:\u003c\/strong\u003e Built for consistent performance in both indoor and outdoor professional environments.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003eQ\u0026amp;A\u003c\/h5\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003e\u003cspan\u003eQ: What is the PCE-428 Class 2 Sound Meter used for?\u003c\/span\u003e\u003c\/strong\u003e\u003cbr\u003e\u003cspan\u003eA: The PCE-428 is designed to measure and analyze noise levels for workplace safety, environmental monitoring, industrial inspections, and acoustic assessments.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003e\u003cspan\u003eQ: Is the PCE-428 compliant with professional noise measurement standards?\u003c\/span\u003e\u003c\/strong\u003e\u003cbr\u003e\u003cspan\u003eA: Yes.
