PCE-430 is a class 1 data-logging sound level meter that meets IEC 60651:1979, IEC 60804:2000, IEC 61672-1:2013, ANSI S1.4-1983 and ANSIS1.43-1997 requirements. This portable high-accuracy sound level meter has a large easy-to-read illuminated LCD screen that displays thesound pressure level (SPL) numerically and graphically in real time. Thanks to octave band filtering, even the slightest difference in frequency isdetected.

The handheld meter also functions as a data logger, recording measurementsat an adjustable interval from 1 s ... 24 h and storing the recordedmeasurement 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 dataanalysis.

This device measures from 22 ... 136 db(A) at a frequency of 3 Hz ... 20 kHz. The meter features A, B, C and Z frequency weightings as well asfast, slow and impulse time weightings. The PCE-430 decibel meter is commonly used by professionals to ensure compliance withenvironmental noise regulations and workplace noise permissible exposure limits. It is also ideal for airport and air force base noise monitoringprograms.
