Integrating average sound level meter (noise meter)
"LA-1411/LA-1441 (Class 2, standard sound level meter)" and
The three products in the "LA-4441 (Class 1, precision sound level meter)" category are:
Complies with the Measurement Law (enacted in 2015) and JIS C 1509-1:2005.
With a wide linearity range of 100 dB, it can simultaneously measure, select, and display seven noise indicators, including time-averaged sound level, in response to a wide range of sound volume fluctuations without switching level ranges.
These three products allow you to separate the microphone unit from the main unit of the sound level meter and connect a dedicated coaxial cable to extend the microphone unit over long distances.
Features
Complies with the Measurement Law (enacted in 2015) and JIS C 1509-1:2005.
Simultaneously measures and displays seven noise indices, including time-averaged sound level (Leq).
Equipped with a time-averaged sound level (Leq) measurement function, essential for noise measurement, it simultaneously measures seven noise indices (Lp, Leq, LE, Lmax, Lmin, Lpeak, LN <Lhigh, L5, L10, L50, L90, L95, Llow, Lave>).
Selective display prevents measurement errors.
The microphone and main unit of the sound level meter can be separated and extended over long distances using a dedicated coaxial cable.
The microphone and main unit of the sound level meter can be separated and extended over long distances using a dedicated coaxial cable. This makes it easy to perform measurements remotely.
