SC-2500A

SC-2120

  • 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-2500A 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.
  • Cost-effective model.
  • Conforms to IEC 60942:2003 Class 2, JIS C 1515:2004 class 2
  • Dynamic speaker type
  • Simple type for quick operation check, cost-effective model
