PCE 430 Class 1 Decibel Sound Meter (22 - 136dB) - PCE-430
The PCE 430 Class 1 Decibel Sound Meter (22 - 136dB) complies with IEC 60651:1979, IEC 60804:2000, IEC 61672-1:2013, ANSI S1.4-1983, and ANSI S1.43-1997 standards. This portable, high-precision sound level meter features a large, easy-to-read LCD screen that displays the sound pressure level (SPL) both numerically and graphically in real time. With octave band filtering, it is capable of detecting even the smallest frequency variations.
This 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.
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 as fast, slow and impulse time weightings. The PCE-430 decibel meter is commonly used by professionals to ensure compliance with environmental noise regulations and workplace noise permissible exposure limits.
