Deskripsi
Sound Level Meter Data Logger USB Alat Ukur Suara Data Logger
Dengan memory yang cukup besar untuk menyimpan data yang kemudian bisa di olah dan di analisa di komputer.
This Digital Sound Level Meter is an instrument to measure Sound Pressure Level in decibels (dB).
This meter is featured with wide measuring range (30 ~ 130 dB), Bar-Graph Indication, A/C frequency weighting, Fast / Slow response and Maximum Hold function.
Moreover, the meter can connect to PC for Data Logging with optional USB cable.
This is a portable, easy to use and handy instrument for sound quality control in office, home, school and construction site. The meter has wide range of applications such as noise pollution studies, research and other industrial use.
