Sound Level Meter Digital Portable Decibel Meter 30dB to 130dB A/C Weighted LCD Display Can Be Used at Home, Factory and Road
Product Features
- Accurate measurement and fast response: This product is a high-precision sound level meter with a measuring range of 30dB to 130dB and accuracy of 1.5dB (sound pressure standard, 94dB@1kHz). Please note: it is normal for the screen to display 30-40 decibels in a quiet room. The decibel level of normal conversations is 40-60 decibels
- A/C weighted measurement: A-weighted simulates the frequency characteristics of low intensity human ear noise and is suitable for detecting ambient noise. C-weighted simulates the frequency characteristics of high-intensity human ear noise and is suitable for sound pressure analysis of machine motors and machines. The digital display is a 4-digit LCD display with a resolution of 0.1 dB. A more professional measurement method offers you a more perfect experience.
- Fast/slow measurement conversion: the sound level meter has the function of converting fast and slow response speeds. The fast response speed uses a time constant of 125 milliseconds for general environmental measurements. The slow response speed takes a time constant of 1 second and is used for ambient measurements where the noise level changes greatly.
- Widely used: QLUUE sound level meter instrument that measures ambient noise level. It can be used in homes, factories, hotels, construction sites, schools, municipalities, offices, roads, hospitals, laboratories, theatres and audio systems. It is an important tool for monitoring, controlling and testing the sound level of any environment.
- Maximum value and data lock: press the MAX button during measurement to lock the measured maximum value. Short press HOLD to lock the data. If no operation is done within 10 minutes, the sound level meter will automatically shut off. Package includes: 1 x sound level meter, 1 x sponge ball, 3 x 1.5 V AAA batteries, 1 x user manual (English language not guaranteed).
