430 Class 1 Data-Logging Sound Level Meter
Portable high-accuracy decibel meter with 1/1 octave band filter (optional 1/3 octave band filter upgrade) / Includes factory calibration certificate according to ISO 9001
 
Introduction Video 
 
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 ANSI S1.43-1997 requirements. This portable high-accuracy sound level meter has a large easy-to-read illuminated LCD screen that displays the sound pressure level (SPL) numerically and graphically in real time. Thanks to octave band filtering, even the slightest difference in frequency is detected.
 
The handheld 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 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 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 430 decibel meter is commonly used by professionals to ensure compliance with environmental noise regulations and workplace noise permissible exposure limits. It is also ideal for airport and air force base noise monitoring programs.
