The precision sound level meter is a universal sound level meter that measures the exponential time
weighted sound level. Its performance is in accordance with GB/T 3785-2010 standard level 1 And IEC 61672:
2013 Class 1 sound level meter requirements. It also meets the JJG 188-2017 standard.
* The two time weighting F and S 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.
