4-in-1 decibel meter: This 4-in-1 decibel meter not only measures the noise level, but also provides temperature and humidity values in real time on an LCD screen, helping you better understand and manage your environment. It can also be used as a clock with accurate time keeping. LCD display: the desktop decibelmeter has an extra large LED display that can be clearly seen on the screen to show the value. The screen brightness can be adjusted manually by pressing the left button to reduce the brightness and the right button to increase the brightness. You can adjust it at any time according to the change of background light. Accurate measurement: With a sound level range of 30-130 dB and an accuracy of ±1.5 dB, this meter covers frequencies from 35 to 8.5 kHz. It also accurately measures humidity (20-85%) and temperature (-10°C-60°C). Please note that due to different environmental conditions, a deviation of 0-15% of the measured values is considered normal. Long lasting battery life: Powered by a built-in rechargeable 2000 mAh Li-ion battery, this decibel meter provides 24 hours of continuous operation after a 2 hour charge, making it ideal for long-term monitoring without frequent charging. Wide applications: it is suitable for use in the bedroom, living room and other home environments. It can also be used in classrooms, libraries, offices and other public places. It allows you to know the volume level in real time and minimise noise pollution. › See more product details; Product description 1. 4 in 1 decibel meter: using acoustic chips and accurate measurement technology shows in real time on an LCD 2.
