Decibel Meter, CURCONSA SPL Meter, Portable Sound Level Meter, 30dB to 130dB, LCD Display, can be Used in Homes, Factories and Streets（Blue）

  • ...ter is 30dB to 130dB with fast response speed and stable and reliable performance. Sound level meter is a high-precision noise meter with an accuracy of ± 2.0 dB. Real-time monitoring can give you accurate data on the sound level in the area.
  • ❤【A / C Double-weighting Measurement】 The A-weighting simulates the frequency characteristics of low-intensity human ear noise, which is suitable for the detection of ambient noise. The C-weighting 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 Response Rate Conversion】 The spl 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 rate uses a 1 second time constant, which is used for environmental measurements with relatively large changes in noise levels.
  • ❤【Maintain the Maximum Value】Long press the MAX key to lock the maximum value measured during the measurement. Note that db meter does not have data logging and saving capabilities. If there is ....
