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.
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.
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.
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.
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.
