HS5618A Integral Sound Level Meter (and complete set)Detailed product description：

1、 Overview:
The HS5618A integrated sound level meter is a pocket sized intelligent noise measurement instrument innovatively developed according to the requirements of the new national sound level meter standard. Its main performance meets the requirements of the JJG188-2002 Sound Level Meter Verification Regulations and IEC61672 standard for level 2 sound level meters. This sound level meter adopts a 64 × 128 dot matrix large screen LCD display clock, which can automatically measure according to the set time. The measurement data can be stored and transmitted to the HS4782 printer or computer for processing through the RS-232C interface. There are many innovations in the design, which can meet various measurement requirements. This instrument is convenient and reliable for measuring and reading, and can be widely used for measuring various types of noise in environmental monitoring, health and epidemic prevention, labor protection, schools, scientific research, etc.
