The PCE-428 is a class 2 sound level meter that meets the requirements of IEC 60651: 1979, IEC 60804: 2000, IEC 61672-1: 2013, ANSI S1.4-1983 and ANSI S1.43-1997 standards. This high-precision portable sound level meter features a large, easy-to-read backlit LCD display that displays the sound pressure level (SPL) numerically and graphically in real time. Thanks to the octave band function, even the slightest difference in frequency is detected. At the same time as a spectrum analyzer, the frequency of the sound is displayed on the screen and this is done thanks to the 1/1 octave band function, which detects even the slightest difference in frequency.
The sound level meter also functions as a data logger, recording and storing measurements at adjustable intervals from 1 s ... 24 h on a micro SD memory card. In addition to the SD card, the user has the option to transfer the data to a computer via the USB port. Finally, the meter comes with software to process the data.
The capabilities of the PCE-428 meter are enhanced by the fact that it is aimed at auditors of working conditions who must comply with environmental regulations for permissible noise exposure limits in the workplace.
