PCE 430 Class 1 Decibel Sound Meter (22 - 136dB)

Highlights: Class 1 Measures from 22 - 136 db(A) at a frequency of 3 Hz - 20 kHz Portable Maximum accuracy 1/1 octave band filter (optional 1/3 octave band filter upgrade) The PCE 430 Class 1 Decibel Sound Meter (22 - 136dB) meets IEC 60651:1979, IEC 60804:2000, IEC 61672-1:2013, ANSI S1.4-1983 and ANSI S1.43-1997 requirements. 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 & graphically in real time. Thanks to octave band filtering, even the slightest difference in frequency is detected. 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.
