• Application scope and characteristics:

HS5633BThe universal sound level meter is innovatively developed according to the requirements of the new standard for sound level meters. It is equipped with A and C frequency weighting networks, maximum value maintenance, high and low range, overload and underload digital indicators, and AC/DC signal output functions. It is suitable for measuring environmental, traffic noise, mechanical and electrical noise, as well as for building acoustics, electroacoustic measurements, and other applications. The instrument has stable performance, is easy to use, and has the advantages of compact structure, small volume, and light weight. Specially suitable for on-site measurement of various types of noise. The instrument performance meets the requirements of Level 2 in the JJG188-2002 Sound Level Meter Calibration Regulations and IEC61627 Sound Level Meter standards.
