Digital Sound Meter, Noise Level Meter 30-130dB

Functionality: Equipped with a large high-definition LCD screen, this decibel meter measures sound levels and also functions as a thermometer, hygrometer, clock, and timer. Its A-weighted SPL meter is designed to mimic the human ear's sensitivity to low-intensity noises, suitable for ambient noise monitoring. Precision Measurement: The sound level range is 30 to 130 dB with an accuracy of 1.5 dB, covering frequencies from 35 to 8.5 kHz. It measures humidity (20 to 85%) and temperature (-10°C to 60°C or 14°F to 140°F). Please note that due to varying environmental conditions, slight deviations in readings are normal. Long-Lasting Battery Life: The desktop decibel meter is powered by a built-in 2000mAh lithium battery, offering 3 to 5 days of continuous use and up to a week on standby. It is suitable for monitoring in settings such as studios, classrooms, and industrial environments. User-Friendly Interface: Adjusting settings is straightforward. Enhance brightness with the left button, reduce it with the right button, and hold the M button to set the time. Temperature readings can be switched between Celsius and Fahrenheit, making this device easy to use on any desktop. Important Usage Information: Each unit is calibrated and tested before shipment, which may result in the battery not being fully charged upon arrival. The battery indicator shows red during charging and turns green when fully charged, ensuring you are aware of the power status.
