Product OverviewThe Smart Sensor AR824 Sound Level Meter is a professional-grade digital noise measurement device engineered for precise sound pressure level analysis. It is widely used by safety engineers, environmental analysts, and industrial technicians to quantify noise pollution in diverse settings, including factories, construction sites, offices, and aircraft environments. The device combines a high-quality condenser microphone with advanced digital processing to deliver stable, accurate readings even in challenging industrial environments. Key Features Dual-Weighted Monitoring: Supports both A-weighting (for human hearing sensitivity) and C-weighting (for flat response analysis of mechanical noise). Dynamic Response Modes: Features selectable Fast and Slow time-weighting, allowing users to accurately capture both sudden noise spikes and averaged noise levels. High-Visibility Display: Equipped with a large, 5-digit backlit LCD screen and a 50dB scale bar graph, ensuring easy interpretation of data in low-light conditions. Versatile Analysis: Includes Maximum (MAX) value hold, auto power-off to conserve battery life, and range selection modes to tailor the meter to your specific measurement requirements. Rugged & Portable: Designed for field use, the handheld, ergonomic structure is suitable for both indoor and outdoor inspections.
