Description
With a wide linearity range of 100 dB, it can simultaneously measure and selectively display seven noise indices, including time-average sound level, in response to a wide range of sound volume fluctuations without switching the level range.
By separating the microphone section of the sound level meter from the main body and connecting a dedicated coaxial cable, the microphone section can be extended over long distances.
The curved body reduces the effects of sound reflection, and the easy-to-read, intuitive operation menu provides functionality and an easier-to-use human interface than ever before.
In addition, by using dedicated free software, the LA-1441A and LA-4441A sound level meters (sound level meters) can quickly and easily transfer acquired measurement data to a PC via RS-232C or USB, and can also remotely operate and control the sound level meters from a PC.
