Accurate Sound Level Meter LSDM-A10 is a universal sound level meter that measures the exponential time weighted sound level. It has Φ 12.7 mm (1/2) test condenser microphone and ranges from 25 dB to 130dB (A) with control range manual, three gears, linear range > 60 dB. Designed with Large screen dynamic LCD, instantaneous sound level, with analog am meter display. Digital detection technology is used to replace some traditional sound level meter, stability and reliability are greatly improved.
