English Introduction： The HS-5618/HS5618 Integrated Sound Level Meter is a compact and intelligent noise measurement instrument widely used in environmental monitoring, health and epidemic prevention, labor protection, schools, and scientific research. This instrument adopts advanced digital technology and microcontroller control to achieve accurate noise measurement and data processing. Its main technical parameters include a frequency range of 20Hz to 12.5kHz, a measurement range of 35dB to 130dB, and A and C frequency weightings as well as F (fast) and S (slow) time weightings. The HS-5618 sound level meter also features automatic measurement functions, capable of measuring instantaneous sound level Lp, equivalent continuous sound level Leq, maximum sound level Lmax, sound exposure level Lae, and noise dose DL. The measurement time can be automatically set to 10 seconds, 1 minute, 5 minutes, 10 minutes, 15 minutes, 20 minutes, 1 hour, 8 hours, and 24 hours, and in manual mode, it can be set to any time up to a maximum of 24 hours. The instrument is equipped with an internal clock that displays the year, month, day, hour, minute, and second in real time and can automatically store 1000 sets of single data and 64 sets of hourly data. In addition, the HS-5618 sound level meter features a 128×64 dot matrix LCD screen, providing a user-friendly interface and intuitive data reading. Through the RS-232C interface, measurement data can be transferred to a printer or computer for further processing. The instrument is powered by five AA high-energy alkaline batteries or an external DC9V power supply. With dimensions of 307mm×80mm×30mm and a weight of only 386g (excluding batteries), it is portable and convenient for on-site operations.
