AWA5662 Multifunctional Sound Level Meter

Class 1 multifunctional sound level meter designed for industrial machinery noise, factory environmental noise, and workplace noise measurement. Available in four types: Basic, Integral Measurement, Sound Exposure (Dose), and Statistical Type, covering different application scenarios. Complies with IEC61672-1:2013 Class 1, IEC61260-1:2014 Class 1, and IEC61252:2025 standards (depending on configuration). 115 dB ultra-wide linear range with no need for manual range switching. Supports optional 1/1 and 1/3 octave real-time spectrum analysis for advanced acoustic evaluation. 2.4-inch color display with multi-parameter real-time measurement and intuitive operation. Built-in recording and data storage functions (WAV/MP3 optional), with data export for PC analysis. Supports multiple microphones for low to high sound level measurement applications. Supports key industrial and occupational noise indicators such as Leq, Lmax, LE, TWA, LEX,8h, DOSE, and statistical analysis. Compact and portable design (approx. 340 g) with battery or external 5V power supply.
