Sound Level Meter, CURCONSA Sound Level Meter, Portable Decibel Meter, 30 dB to 130 dB, LCD Display, Can Be Used in Private Homes, Factories and Streets
Widely used: a sound level meter is an instrument for measuring ambient sound levels. It can be used in households, factories, workshops, schools, residential areas, offices, streets, hotels, hospitals, laboratories, theatres and sound systems. The range of applications is very wide and an indispensable tool in life.
High accuracy: the measuring range of the dB knife device is 30 dB to 130 dB. Note that it is normal for the screen to display 30-40 decibels in a quiet room. The decibel level for normal conversations is 40-60 decibels. This product is a high-precision db knife device with an accuracy of ±2.0 dB.
A/C double weight measurement: The A-weight simulates the frequency characteristics of low intensity human ear noise, which is suitable for detecting ambient noise. The C weighting simulates the frequency characteristics of high-intensity noise of the human ear, suitable for sound pressure analysis of machine motors and machines. More professional measurement methods offer users 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 speed uses a time constant of 1 second, which is used for ambient measurements with relatively large changes in noise values.
Lock maximum value: long press the MAX button to lock the maximum value measured during measurement. Please note that the sound level meter has no function to record and store data. If there is no operation within 10 minutes, the sound level meter switches off automatically.
