Decibel Meter, Tadeto Digital Sound Level Meter Portable SPL Meter 30dB to 130dB Backlight LCD Display, MAX/MIN Noise Measurement, Data Hold, A/C Mode for Classroom, Office, Factory
- ...sound level meter is 30dB to 130dB and shifting function(5 adjustable measurement ranges) . Highly accurate with ± 1.5 dB. Real-time monitoring can give you accurate data on the sound level in the area..
- 【A/C Weighted Measurement】 The A weighted simulates the frequency characteristics of low-intensity human ear noise, which is suitable for the detection of ambient noise. The C weighted simulates the frequency properties of high-intensity 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 sound level meter has the function of converting the fast and slow response rate. The fast response rate uses a time constant of 0.125s/time for general environmental measurement. The slow response rate uses a 1s/time 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..
