Sound Level Meter HY118A

The HY118A type integral average sound level meter is a handheld instrument whose performance complies with the national standard GB/T 3785－2010 and the international standard IEC 61672:2013 "Sound Level Meter" for class 2 X class time average sound level meter and integrated sound level meter. The requirements of the scale. This sound level meter is the company's latest all-digital sound level meter. It is lightweight and portable. It is suitable for on-site measurement of mechanical and electrical product noise, environmental noise, traffic noise, and workplace noise. It can also be used for university teaching demonstrations.

The HY118A integral average sound level meter is an improved product of the HY108B sound level meter. It has a manual integral average function. It is mainly used to measure the time-weighted sound level, sound exposure level, cumulative percentage sound level, sound exposure and Noise evaluation amount of noise dose. The HY118A sound level meter uses the internal memory to save only one integral measurement result, and it will not be lost after power off. After each measurement, it will automatically cover the last result and save it, and the measurement result can also be printed on site.
