Decibel Meter,Digital Sound Level Meter 30-130db - XN

Functionality: Equipped with a large high-definition LCD screen, this decibel meter not only measures sound levels but also acts as a thermometer, hygrometer, clock, and timer. Its A-weighted SPL meter is specifically designed to mimic the human ear's sensitivity to low-intensity noises, making it ideal for ambient noise monitoring. Precision Measurement: With a sound level range of 30 - 130 dB and an accuracy of 1.5 dB, this meter covers frequencies from 35 to 8.5KHz. It also accurately measures humidity (20~85%) and temperature (-10C - 60C or 14-140). Please note, due to varying environmental conditions, a deviation of 0~15% in readings is considered 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's perfect for prolonged 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 long- 'M' to set the time. Temperature readings can be switched between Celsius and Fahrenheit, making this device adaptable and easy to use on any desktop.
