These sound level meters were designed with an emphasis on “measuring while listening to sound” in addition to the original features of measurement and calculation. By adding various options, the LA-3000 can be upgraded to an analyzer, a recorder, and a comparator, performing more than just a sound level meter. You can check the proper recording of data and the condition of the object via headphones, and see the analysis waveform on the large easy-to-see screen in order to carry out reliable measurement confidently at a site that does not permit any failure. Measurement, recording, analysis, and checking can be performed by a single item of equipment, thereby improving the measurement efficiency substantially. For more detailed analysis, analysis software made by Ono Sokki is useful such as waveform analysis, sound quality evaluation, or fluctuation sound analysis.

LA-3570 Class 1 (high sensitivity type)	Suitable for measuring small sounds in a sound insulating box or similar environment etc.
LA-3560 Class 1 (wide band type)	Suitable for making measurements across the entire audible range
LA-3260 Class 2	Suitable for measuring environmental noise up to 8 kHz

Features

3.5-inch large easy-to-see screen
Direct keys for easy operation
Wide linearity range of 110 dB, no need of range switching
Quad-channel screen (Up to four different sound level calculation results can be displayed simultaneously.)
Enables to measure while listening, and record the sound under measurement
Adding options can upgrade the models into higher performance device to serve as an analyzer, a recorder, and a sound comparator. Measurement, recording, analysis and judgment all with the same device
Conforms to IEC 61672-1, JIS C1509-1
