    Product Description

    The AWA5662 multifunctional sound level meter is mainly designed and manufactured for industrial enterprises to measure and analyze noise from machinery and equipment and factory noise. It comes in three different configurations based on its functions, suitable for measuring noise from machinery and equipment, factory environmental noise, and workplace noise, respectively. Specifically:
    AWA5662-0 Basic Type: Measures only instantaneous sound levels, as machinery and equipment noise is almost always steady-state noise, thus significantly reducing the instrument's price;
    AWA5662-1 Integral Measurement Type: Measures equivalent (average) sound levels, suitable for measuring fluctuating and unstable noise (e.g., factory boundary noise), and also allows for data storage, retrieval, and recording; 
    AWA5662-2 Sound Exposure Measurement Type: Primarily used for measuring workplace noise, and also allows for data storage, retrieval, and recording;
    AWA5662-3 Statistical Type: Primarily used for environmental noise measurement, equipment noise characteristic research, etc., and also allows for data storage, retrieval, and recording.
    All models can be equipped with 1/1 octave and 1/3 octave real-time spectrum analysis functions, and different microphones can be replaced to adapt to low-level or high-level sound measurement.
