LSENLTY Plug-in Noise Detector-L6101

【A-Weighting Function】High-precision sensor with professional A-weighting simulates human ear response. Measures dBA to accurately reflect noise impact on the body – sensitive to low-level home noise fluctuations.
【Plug-in Design】Upgraded plug-in design eliminates battery aging and short battery life issues. Compatible with all standard US 110V–220V AC outlets – ideal for communities, homes, libraries, classrooms, etc.
【Max/Min Noise Level】Built-in memory records max and min noise levels over 24 hours. Double-click the "O" button to view the previous 24-hour max/min readings for easy noise monitoring.
【Fast/Slow Response + Data Hold】One-key switch between fast/slow response rates. Long-press "H" to change detection frequency; short-press to hold and display the current noise value.
【3-in-1 Accurate Measurement】Monitors noise (30–130dBA, ±1.5dBA), temperature (-10℃~50℃ / 14℉~122℉, ±1.5℃), and humidity (0%–95% RH, ±5%). Wide range, high precision – provides comprehensive environmental data.
【Smart Brightness Design】Three brightness levels adjustable by short-pressing the "☀" button. Even with screen off, the device continues monitoring – indicator light flashes every 30 seconds to show normal operation.
【2.1-inch Display Screen】Clear 2.1-inch HD color screen shows noise value in decibels. Color‑coded visualization helps quickly assess noise levels. Simple, intuitive, and easy to operate.
