Decibel Meter, Sound Level Meter, Portable SPL Meter, 30dB to 130dB, LCD Display, Used in Homes, Schools, Factories and Streets

This small, stylish, light-weight and portable noise meter can be widely used in noise detection in various environments such as health prevention and noise engineering, such as homes, factories, traffic roads, cars, baby rooms, and sound system offices, schools and construction sites, etc.
 

Product Features:

【Widely Used】 A sound level meter is an instrument used to measure ambient sound levels. It can be used in homes, factories, workshops, schools, residential areas, offices, streets, hotels, hospitals, laboratories, theaters and sound systems, the scope of application is very wide and an indispensable tool in life.

【High Precision】 The measuring range of the sound level meter is 30dB to 130dB with fast response speed and stable and reliable performance. This product is a high-precision noise meter with an accuracy of ± 1.5 dB. Real-time monitoring can give you accurate data on the sound level in the area.

【A-weighting Measurement】 The A-weighting simulates the frequency characteristics of low-intensity human ear noise, which is suitable for the detection of ambient noise. More professional measurement methods provide users with a more perfect user experience.

【Fast and Slow Response Rate Conversion】 The sound level meter has the function of converting the fast and slow response rate. The fast response rate uses a time constant of 125 milliseconds for general environmental measurement. The slow response rate uses a 1 second time constant, which is used for environmental measurements with relatively large changes in noise levels.

【LCD Screen】 The display is a LCD digital display with backlight which offers quicker reading of the measured values in dark places. Long press the FAST/SLOW key to turn the backlight off or on. When the battery is low, the LCD display will display a low voltage icon, indicating that the power is low now and the battery needs to be replaced. 

Product Highlights:

1.This is a small, fashionable, light-weight and portable noise meter, which is widely used in noise detection for health prevention and noise engineering in various environments such as homes, factories, traffic roads, cars, baby rooms and stereos system offices, schools and construction sites, etc.

2. The measurement range of this noise meter is 30dB to 130dB, and the high precision is ±1.5 dB. Real-time monitoring can give you accurate data on sound levels in the area.

3. A-weighting simulates the frequency characteristics of low-intensity human ear noise, detects environmental noise, and provides users with accurate noise data.

4. The noise meter has the function of changing the speed of response. Fast response speed is only 125 ms response time for fast measurement. The slow response is measured with a response speed of 1 second. So it is suitable for various measurement needs.
