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

  • ...】 The measuring range of the sound level meter 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 ....
