Multifunctional Decibel Meter: This precision noise detector monitors noise levels within a 30-130dBA range with ±1.5dBA accuracy, temperature from 14°F-122°F, and humidity between 20%-85%. Equipped with 0.1dBA resolution and 1s sampling rate, it provides comprehensive and precise environmental data. Intuitive Display with Visual Alarms: Features a large LED screen that displays dB value, temperature, humidity, a 24-hour clock, and date. It includes a 6-level color-coded noise bar, temperature alert icons, and indicators for low-battery and charging status, ensuring all critical information is visible at a glance. Versatile Mounting Options: The sound level meter can be placed on a desktop using its back bracket or mounted on a wall with included stickers and screws. This flexibility makes it suitable for various spaces and user preferences, ensuring optimal placement and functionality. A-Weighted Functionality: Our sound level meter is equipped with A-weighting, designed to simulate the sensitivity of the human ear to sound. This feature ensures that noise measurements correlate closely with human perception of loudness, providing results that are both relevant and reliable. Wide Application: Ideal for monitoring indoor environments such as homes, classrooms, offices, schools, baby rooms, factories, and theaters. It is also effective for assessing noise levels from noisy neighbors, helping maintain comfortable and healthy sound levels in diverse settings.
