Feature:
1. 4 IN 1 DECIBEL METER: This decibel meter has multiple functions, having a decibel meter is equivalent to having a thermometer, hygrometer and clock at the same time.
2. 11IN DISPLAY SCREEN: This large screen decibel meter has an 11 inch LED display with adjustable brightness for a clear, easy to use display.
3. HIGH ACCURACY: The sound level meter uses an intelligent air semiconductor sensor to test decibel temperature and humidity values, making it more sensitive, accurate and stable.
4. WIDE APPLICATION: The sound level meter can be applied to noise engineering, product quality control, health prevention and treatment, etc.
5. USB CHARGING: This decibel meter has a built in 2000mAh lithium battery power supply with a 10ft USB charging cable so you can charge it anywhere.
