LA-1411 ●Noise meter Class 2 (ordinary sound level meter) for measuring sound pressure level...
ONOSOKKIPrecision noise meter1441AThe three types of equivalent noise level noise meters, "LA-1411/LA-1441A (Class 2, ordinary sound level meter)" and "LA-4441A (Class 1, precision sound level meter)", all comply with the international electrical standard IEC 61672-1:2013, Japanese industrial standard JIS C 1509-1:2017 and Japanese Measurement Law (implemented in 2015), have a wide linear range of 100dB and can adapt to noise fluctuations of different sizes without switching, and can simultaneously measure and display 7 noise indicators including equivalent noise level noise. In addition, the microphone of the noise meter is separated from the main body, and a dedicated coaxial cable is used to measure at a long distance. The curved shape of the housing reduces the influence of sound reflection, and the intuitive operation menu realizes a better human-machine interface. In addition, using dedicated software, the measured data can be easily remotely operated by a computer via RS-232C or USB. The standard configuration includes the measurement function of the equivalent noise level (Leq), which is indispensable for noise measurement. Seven noise indicators (Lp, Leq, LE, Lmax, Lmin, Lpk, LN<LHI, L5, L10, L50, L90, L95, LLO, LAV>) can be measured at the same time and selected for display to prevent accidental omission of measurement items. ◆ Lp time-weighted noise level ◆ Leq equivalent noise level ◆ LE single-shot noise exposure level ◆ Lmax maximum time-weighted noise level ◆ Lmin minimum time-weighted noise level ◆ Lpk peak sound pressure level ◆ LN time rate sound pressure level LA-1411 ●Class 2 noise meter for mechanical noise sound pressure level or product inspection (ordinary sound level meter) ●Inexpensive, high-performance model LA-1441A ●Class 2 noise meter for working environment and environmental noise measurement (ordinary sound level meter) ●Automatic measurement function with timer or trigger ●Can record sound pressure level history trend, and the saving interval starts from 1ms (Lp recording function) ●Equipped with USB and RS-232C interface LA-4441A ●Class 1 noise meter for noise analysis and product quality inspection (precision sound level meter) ● Standard configuration can correspond to the time weighting characteristics of 10ms and IMPULSE for rapid sound pressure level changes ● Can record the trend of sound pressure level history, and save the interval starting from 1ms (Lp recording function) ● Equipped with USB and RS-232C interface
