The AcoustiCal AC-300 is a precision sound level calibrator for calibration of Class/Type 1 instruments. It generates two settings with either 250 Hz or 1000 Hz at a sound pressure level of 114 dB. The sound pressure level and combinations of frequency outputs conform to the requirements of the IEC standard 60942 (2003) for sound calibrators.

  • Specifically designed for field calibration of 3M sound level meters and noise dosimeters across a wide range of temperature, humidity and pressure conditions
  • Produces two signals — 250 Hz or 1,000 Hz at a sound pressure level of 114 dB
  • Single On/Off/Function key leads to fast calibrations
  • Simply insert the microphone of your instrument, select the correct signal from the one-button keypad and calibrate
  • Conforms to the requirements of IEC 60942 (2003-01) for sound calibrators and ANSI S1.40-2006 (R2011)specifications and verification procedures for sound level meters
  • Auto-Off function powers down 4 minutes after last key press, reducing power drain and saving battery life
