The SC-2500 acoustic calibrator is an acoustic calibrator that conforms to JIS C 1515:2004 (Electroacoustics - Acoustic Calibrators) Class 1.
By employing a sound pressure feedback control system, fluctuations in sound pressure levels due to static pressure are controlled, ensuring stable sound pressure even when the operating environment changes.
We've set an affordable price so that you can use it for daily acoustic calibration.
Please use this for inspecting and maintaining sound level meters that comply with JIS C 1509-1:2005 (Sound level meters) and JIC C 1516:2014 (Sound level meters - for trade or certification).
