ONOSOKKIPrecision sound level meter noise meterLA-7500The LA-7000 series high-function sound level meter uses a large-size color LCD touch screen, and the operability is greatly improved. You can use the sound level meter to start measuring with simple and intuitive operation. In addition to measuring and analyzing noise levels, the LA-7000 series high-function sound level meter can monitor the noise being measured during the measurement process. By monitoring, you can confirm the state of the object being measured, detect the sound source, and confirm the recording status, so that you can complete the measurement with peace of mind and certainty. In addition to measuring and analyzing noise levels, the LA-7000 series high-function sound level meter can monitor the noise being measured during the measurement process. At the same time, if you use the optional function, on the basis of sound pressure level measurement, it can also have noise analysis*, spectrum analysis*, sound recording* and other functions. (*Optional function) The LA-7000 series high-function sound level meter can complete multiple measurement and analysis such as noise measurement, noise recording, spectrum analysis, and abnormal sound source detection with only one unit, which can greatly improve the work efficiency of measurement and analysis. The LA-7000 series high-performance sound level meter records and stores sound data, and analyzes and processes it in combination with our various products to meet a variety of needs such as time waveform analysis, sound quality evaluation analysis, jitter noise analysis, and sound spectrum simulation.
