Description
🌟【Precision Measurement & Wide Range】With a high accuracy(+/-1.5dB,0.1 dB resolution) and a wide measurement range(30dBA-130dBA),the noise level meter is a useful device for you to measure the noise of running machines,music ,neighbor or speech therapy and so on..🌟【More Intelligent Functions】Automatic power off function plays an important part in eliminating waste of electricity.Furthermore,low power indication is designed to remind you to replace battery in time..🌟【Auto Power Off & Overload Indication】Max hold function is able to freeze the max recording and over-range measurement warning sign is designed for guiding you to select the correct range (30-80dB;50-100dB;60-110dB;80-130dB)according to real reading.And self-check function will keep 10 seconds for each opening opportunity..🌟【Convenient for Further Analysis】There are output interfaces (AC/DC output) on the side of noise measurement device,which can be better connected with other devices,such as X-Y axis recorder or frequency analyzer for statistical analysis..🌟【Meet Different Test Conditions】Frequency weighting C is suitable for measuring mechanical noise and A for the noise felt by human ear.Furthermore,there are two time weightings ,including “Fast”for real-time measurement and “Slow” for average noise volume.
