Brief introduction: HS5628B personal sound exposure meter is not only a universal sound level meter that can measure the weight sound level of the exponential time meter, but also an integrated sound level meter that can measure the time average sound level and a personal sound exposure meter that can measure the sound exposure. Its performance meets the requirements of GB/ t3785-2010 and iec61672-2002 standards for two-level sound level meters. This instrument adopts advanced digital detection technology, which has the advantages of high reliability, good stability and wide dynamic range. Dot matrix liquid crystal display, easy operation for users, battery power supply, measurement results stored in the instrument for a long time, through the rs-232 interface in the field or after the use of a micro-printer printed out or sent to the computer for processing. This instrument is compact in structure, beautiful in shape and has many functions. It can be used for measuring environmental noise, labor protection, industrial hygiene and industrial noise of various machines, vehicles, ships and electrical appliances.
