The HS5910 personal sound exposure meter is not only a universal sound level meter for measuring index time weighted sound levels, but also an integral sound level meter for measuring time averaged sound levels and a personal sound exposure meter for measuring sound exposure. Its performance meets the requirements of GB/T15592-2010/IEC61252:2002 (electroacoustic personal sound exposure meter specification) standards, as well as the requirements of GB/T3785-2010 and IEC61672-2002 standards for level 2 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 LCD display, easy to operate by users, battery powered, and the measurement results are stored in the instrument for a long time. It can be printed on-site or post production using a micro printer through RS-232 interface or sent to a computer for processing.
This instrument has a compact structure, beautiful appearance, and multiple functions, and can be used for measuring environmental noise.
Usage: Suitable for labor protection and environmental noise survey measurement, industrial hygiene, and various machines, vehicles, etc
Measurement of industrial noise from ships, electrical appliances, etc.
