Digital Bluetooth (30 ~ 130 dB) Decibel Noise Measure Sound Level Meter

Specifications

Brief Description

A New Professional Sound Level Meter with Bluetooth!!

This digital sound level meter is a professional instrument to measure Sound Pressure Level in decibels (dB) with range of 30 ~ 130 dB. It is equipped with built-in calibration signal of 94 dB at 1 kHz and offers 4 measurement parameters Lp (sound level), Leq (equivalent continuous sound level), Lmax (maximum sound level), L_N (percent of all readings over alarm value set).

This sound level meter can memorize 30 groups of measurement data and conditions for later use or downloading to PC. It has built-in Bluetooth interface so that users can download data to PC wirelessly and conveniently without installation of software. Downloaded data can be exported to Excel for further analysis. In addition, auto power off is programmable, it can be set and disable and comes with other features such as adjustable alarm set, LED alarm output and auto range selection.

This device is a portable, easy to use and handy instrument for sound quality control in office, home, school, traffic, audio system and construction site. It has wide range of applications such as noise pollution studies, research and other industrial use.
