Wherever you need to monitor noise levels, Tadeto decibe meter will do the job. Accurate Measurement The measuring range of the decibel meter is 30dB to 130dB and shifting function5 adjustable measurement ranges . Highly accurate with 1.5 dB. Realtime monitoring can give you accurate data on the sound level in the area. AC Weighted Measurement The A weighted simulates the frequency characteristics of lowintensity human ear noise, which is suitable for the detection of ambient noise. The C weighted simulates the frequency properties of highintensity 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. Fast and Slow Measurement The decibel meter has the function of converting the fast and slow response rate. The fast response rate uses a time constant of 0.125stime for general environmental measurement. The slow response rate uses a 1stime constant, which is used for environmental measurements with relatively large changes in noise levels. Backlight Display Large backlight 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. Widely ApplicableTadeto decibel meter can be appropriate for noise engineering,product quality control,health prevention and treatment,etc.This audio noise measure device is a great tool for checking, monitoring or controlling and test the sound level of any environments. It is widely applicable for personal, families, business, studies, industrial and etc.
