The HS6298 multifunctional noise analyzer is not only a universal sound level meter for measuring index time weighted sound levels, but also an integral average sound level meter for measuring time averaged sound levels and an integral sound level meter for measuring sound exposure. It can also measure cumulative percentage sound levels (statistical sound levels) and noise levels. Its performance meets the requirements of GB/T3785 and IEC61672-2002 standards for level 2 sound level meters, and its sensitivity to radio frequency fields belongs to Class X.
This instrument adopts advanced digital detection technology, which has the advantages of high reliability, good stability, and wide dynamic range. This instrument adopts a 128 × 64 dot matrix LCD display with background light display, a fully Chinese interface, rich display content, and a menu based operation interface with Chinese character prompt function. It is easy for users to operate, battery powered, and the measurement results can be stored in the instrument for a long time. The measurement results can be printed on-site or sent to a computer for processing through the built-in RS-232 interface.
