Votery Digital Sound Level Meter Hand-held Sound dB Meter with Programmable Alarm Value Function, 30-130dB(A) with LCD Dispaly Decibel Sound Noise Meter Tester Measurement
【Accurate Measurement】 The measuring range of the sound level meter is 30dB to 130dB . Highly accurate with ± 1.5 dB. Real-time monitoring can give you accurate data on the sound level in the area.The microcomputer automatically selects the best measurement gear within the range of 30~130 decibels
【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.
【Digital LCD Display 】 The digital display is a 4-digit LCD display with a resolution of 0.1 dB. Large backlit 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.
