Equipped with USB and RS-232C interface
LA-4441A Sound level meter Class 1
Sound level meter (Class 1) for sound analysis and product testing.
Time weighting (10ms, Impulse) corresponding to the fast sound fluctuation.
Level trend can be recorded at the interval from 1ms. (Lp memory function)
Equipped with USB and RS-232C interfaces
SC−2500
Class 1 Sound calibrator
Conforms to IEC 60942:2017 Class 1, ANSI S1.40-2006 (R2011) Class 1, JIS C 1515:2020 class 1
Used for calibration of Class 1 and Class 2 Sound level meter
Since the SC-2500 uses the sound pressure feedback control method to control fluctuations in sound pressure
caused by static pressure, it can generate a stable sound pressure even if the operating environment changes.
A Sound Level Meter is an instrument used to measure sound levels in decibels. Ono sokki Sound Level Meters use a microphone to pick up sound waves, which are then converted into electrical signals. These signals are processed and displayed as a sound level reading on the meter.
Yes, Ono sokki noise level meters are designed to be portable and user-friendly. They are small and lightweight, and most models have a simple interface that makes it easy to take measurements and read the results.
