AWA5662 Multifunctional Sound Level Meter

Product Description

The AWA5662 multifunctional sound level meter is designed and manufactured for industrial enterprises to measure and analyze noise from machinery and equipment and factory noise. It is a Class 1 meter for industrial machinery noise, factory environmental noise, and workplace noise measurement. Four types are available. AWA5662-0 (Basic) measures instantaneous sound levels. AWA5662-1 (Integral Measurement) measures equivalent (average) sound levels for fluctuating and unstable noise, such as factory boundary noise, and allows data storage, retrieval, and recording. AWA5662-2 (Sound Exposure) is primarily used for workplace noise and allows data storage, retrieval, and recording. AWA5662-3 (Statistical) is primarily used for environmental noise measurement and equipment noise characteristic research, and allows data storage, retrieval, and recording. Depending on configuration, the meter complies with IEC 61672-1:2013 Class 1, IEC 61260-1:2014 Class 1, and IEC 61252:2025. All models can be equipped with 1/1 octave and 1/3 octave real-time spectrum analysis, and microphones can be replaced for low-level or high-level sound measurement.
