W/ AC and DC analog signal outputs, it can be connected to a frequency analyzer or an X-Y axis logger for statistical analysis or data recorders. Measuring Range: 30~130 dBA and dBc High Accuracy: +/- 1.5 dB Resoletion: .1dB Frequency Range: 31.5Hz ~ 8.5K Hz Linerity Rnage: 50dB Display: Large digits, Back light screen Sampling Frequency: 2 times/ Sec Read more Home Theater dB Level Setting Features with A and C frequency-weighting to help you calibrate the home theater, set the sound system dB level. Also to see how loud things are so you know how loud something can be before it disturbs other people. Wanna know if the noise is OFF volume limits? Except A/C weighting, BT-882A also support FAST(125mS) / Slow (1mS) weighting, to help you make accurate measurement in both steady noise and Unstable fluctuation noise High Accuracy dB Level Meter This product is a high- precision phonometer meter with an accuracy of +/- 1.5dB,Measuring range: 30~130 decibels. There’s a calibration button for self-calibration under 94 dB1KHz Indoor and Out Door Sound Meter This Decibel Level Meter is an ideal tool for measuring the ambient sound level,such as noise level around factories, workshops, schools, residential, offices, road, airport, audio etc.It also can be appropriate for noise control （e.g. noise from concert, party, engine, bar, car) product quality control, health prevention and treatment,etc. Read more
Product Features
- Precision Measurement & Wide RangeWith 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 FunctionsAutomatic 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 IndicationMax 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 AnalysisThere 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 ConditionsFrequency weighting C is suitable for measuring mechanical noise and A for the noise felt by human ear.Furthermore,there are two time weightings ,including Fastfor real-time measurement and Slow for average noise volume.
