Sound Level Meter, buy Noise spectrum analyzer DB30-6226E on China Suppliers Mobile

Product Details

Applications】
The Noise Spectrum Analyzer is a universal sound level meter that measures the exponential time weighted sound level, an integrated average sound
level meter that can measure the time average sound level, and an integrated sound level meter that measures sound exposure. It can also measure
Accumulated percentile sound level (statistical sound level), the instrument is also a spectrum analyzer that can measure 1/1 octave filter and 1/3
octave filter, and its performance is in accordance with GB/T3785-2010 standard level 2 And IEC61672:2013 Class 2 sound level meter requirements, but also meet the requirements of IEC1260:2014 Class 2 and GB/T3241-2014
【Features】

* With the function of integration and statistics, 800 groups of single measurement and 6 days of regular measurement can be achieved. The stored data can be read and printed. The collected data can be checked when the regular measurement ispaused.
* The three time weighting F, S, and I can be selected.
* The digital detection technology is used to replace some traditional sound level meters, the stability and reliability are greatly improved.
* Large screen display is adopted, with clear and intuitive display. With dynamic scale display.
* Optional Bluetooth printer for data printing.
* Use USB data output to connect with PC.
* Provide Bluetooth data output choice.
