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 class 1 sound level meter features A, B, C and Z frequency weightings as well as fast, slow and impulse time weightings. This 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.
