| This sound level meter is a great tool for checking, monitoring or controlling the sound level of any environments. It is widely applicable for personal, families, business, studies, industrial and etc. Features:
1.【Accurate Measurement】 The measuring range of the sound level meter is 30dB to 130dB . Highly accurate with ± 1.5 dB. Real-time monitoring can give you accurate data on the sound level in the area. 2.【A/C Weighted Measurement】 The A weighted simulates the frequency characteristics of low-intensity human ear noise, which is suitable for the detection of ambient noise. The C weighted simulates the frequency properties of high-intensity noises of the human ear, which are suitable for the sound pressure analysis of machine motors and machines. More professional measurement methods provide users with a more perfect user experience.
3.【Fast and Slow Measurement】 The sound level meter has the function of converting the fast and slow response rate. The fast response rate uses a time constant of 0.125s/time for general environmental measurement. The slow response rate uses a 1s/time constant, which is used for environmental measurements with relatively large changes in noise levels.
4.【Digital LCD Display 】 The digital display is a 1.6inch LCD display with a resolution of 0.1 dB. Large backlit LCD digital display, the reading effect is clearer in dark places. When the battery is low, the LCD display will display a low voltage icon, indicating that the power is low at this point and the battery needs to be replaced.
5.【Convenient and Lightweight 】AUTOOL sound level meter is lightweight and easy to carry. It's widely used in factories, transportation, car, baby room and audio system offices, sound quality control in homes, schools, and construction sites.
