Experimental equipment manufacturers supply noise analyzer price, [Huasheng] professional development, reliable quality Overview JH8HS6298 multifunction noise tester is a pocket of high intelligence noise measuring instrument, which combines integrating sound level meter, noise statistical analysis meter, noise logger, digital recording several instrument functions in one, in design and function, there are plenty of innovation to meet a variety of measurement requirements. The instrument has a 128 × 64 graphics LCD with backlight display, rich in content and character tips, operator interface with menu, the user can quickly master the operation. The measurement results can be stored in the instrument for a long time, on-site or through the built-in RS-232C interface using a micro-printer afterwards printed out or sent to the computer. This instrument is compact structure, beautiful shape, multi-function, high degree of automation, can be used for the measurement of ambient noise, and can also be used for labor protection, industrial hygiene, and a variety of machines, vehicles, ships, electrical and other industrial noise measurement.
