The Impulse Sound Level Meter is a universal sound level meter that measures the exponential time
weighted sound level, and an impulse sound level meter. Its performance is in accordance with
GB/T 3785-2010 standard level And IEC 61672:2013 Class sound level meter requirements. It also
meets the JJG 188-2017 standard.
* 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.
