C-Timvasion Digital Sound Level Meter, High-Precision Sound Level Measurement, 30-130dBA Volume Meter, Backlit LCD Display, Suitable for Games, Indepe

Digital Sound Level Meter" This sound level meter is applicable to noise engineering, product quality control, health management, and more. It can be used not only for noise measurement at construction sites, but also for recording noise pollution and verifying measurements before vehicle inspections. "Equipped with Temperature Measurement Function/A Dual Weighting Measurement" This instrument is equipped with a temperature measurement function, allowing you to measure ambient temperature. A weighting simulates the frequency characteristics of low-intensity noise heard by the human ear and is suitable for detecting environmental noise. "Fast/Slow Response Speed ​​Conversion" This sound level meter has a fast/slow response speed conversion function. The fast response rate uses a 125 millisecond time constant for general environmental measurements. The slow response rate uses a 1-second time constant for environmental measurements with relatively large noise level changes. "Versatile LCD Screen/Multifunctional" The sound pressure level (SPL) meter has maximum and minimum measurement values ​​that represent the maximum and minimum (high/low peak) values ​​of sound generated within a certain period of time. The data hold function allows you to freeze the current reading according to your individual needs. Please note that this sound level meter does not have a data recording or storage function. "A Dual Weighted Measurement" A weighting simulates the frequency characteristics of low-intensity noise heard by the human ear and is suitable for detecting environmental noise, such as factories, workshops, schools, residential areas, business districts, traffic roads, and acoustics.
