Meishin Koki Co., Ltd.
About This Product
■Summary
・Highly efficient measurement, analysis, and recording while listening to sound
・One unit can measure noise, record sound, analyze frequencies, and locate the source of abnormal noises.
Features
■3 models to suit different uses
・LA-7700 (Class 1): [High sensitivity type] For those who measure small sounds in anechoic chambers, etc. Measurement frequency range: 10 Hz – 20 kHz
・LA-7500 (Class 1): [Wideband type] For those who measure the audible range from ultra-low frequency sounds Measurement frequency range: 10 Hz – 20 kHz / 1 Hz to 20 kHz (when ultra-low frequency function is enabled)
・LA-7200 (Class 2): For those who perform high-performance environmental noise measurement Measurement frequency range: 10 Hz – 8 kHz
■Improved ease of use
・Adoption of touch panel
・One-touch start (memory automatic save) key prevents mistakes such as forgetting to press the save key
・Using USB bus power, it can be used for long periods of time when used in conjunction with AA batteries.
■Improved visibility
・4.3 inch (smartphone equivalent) large color LCD
・Improved visibility such as overwriting
■Improved ease of holding
・35% reduction in volume compared to the previous model (LA-3000)
・While the display screen is large, the main body is easy to hold and has been made smaller.
■Improved functionality
・Simultaneous recording possible during frequency analysis: Recording and analysis can be performed at the same time, leading to shorter measurement times.
・You can compare Allpass sound (sound of all bands) and Bandpass sound (sound of specified frequency band only): AP/BP can be switched in filter mode.
■Function
With the addition of functions, it is now possible to perform frequency analysis and record sound with a single sound level meter, improving the efficiency of measurement work. By understanding not only the noise level but also the frequency characteristics, it is possible to investigate the cause.
