Product Features

• A-Weighting FunctionLSENLTY sound level meter uses a high-precision sensor combined with professional A-weighting noise measurement, accurately simulating the human ear's hearing characteristics. The dBA unit accurately reflects the actual impact of noise on the human body, sensitively capturing subtle fluctuations in low noise levels at home.
• Plug-in DesignUpgraded lsenlty plug-in noise detector overcomes the problems of battery aging and short battery life of traditional decibel meters. It is compatible with all standard US 110V to 220V AC power outlets in communities, homes, libraries, classrooms, and other places.
• Max/Min Noise LevelNoise meter has a memory function that accurately measures and records the maximum and minimum noise levels observed within 24 hours. Double-clicking the "O" button displays the maximum and minimum noise levels recorded in the previous 24 hours, making it convenient to check noise levels.
• Fast/Slow Response + Data HoldSound meter supports one-key switching between fast and slow response rates, combined with a data hold function; long-pressing the "H" button switches the noise detection frequency, and a short press locks and displays the current accurate noise measurement value.
• 3-in-1 Accurate MeasurementTemperature, humidity, and noise multi-dimensional monitoring, real-time and accurate capture of ambient sound level, temperature, and humidity data; noise detection 30-130dBA (1.5dBA), temperature -10C~50C/4F~122F (1.5C/2.7F), humidity 0%-95% RH (5%), wide range and high precision, providing comprehensive environmental data.
• Smart Brightness DesignDecibel reader has three brightness levels, which can be switched by short-pressing the "" button. Even with the screen brightness off, the decibel meter will continue to monitor, and the indicator light will flash every 30 seconds to indicate that the device is in normal monitoring mode.
• 2.1-inch Display ScreenNoise tester is equipped with a 2.1-inch high-definition color screen, and the noise value is clearly displayed in decibels on the LCD screen. The color visualization function allows users to quickly assess the surrounding noise levels. The device is designed to be simple, intuitive, and easy to operate.
