JH8HS6298 multifunction noise tester is a pocket of noise measurement instruments with high intelligence, which sets integrating sound level meter, noise statistics analyzer, noise acquisition, digital records and other functions in one of several instruments in the design and There are many innovative functions to meet a variety of measurement requirements.
This instrument has a 128 × 64 dot matrix LCD display with backlight film to show rich in content, there are Chinese characters prompts, use the menu interface, users can quickly master the operation. Measurement results can be long-term storage in the instrument, through the built-in RS-232C interface using a micro-site or after the printer to print out or go to the computer.
The instrument is compact, attractive appearance, multi-function, high degree of automation can be used for environmental noise measurements can also be used for labor protection, industrial hygiene and all kinds of machinery, vehicles, ships, electrical and other industrial noise measurements.
