  • Type IFC-1 - Infrasound Calibrator Infrasound Calibrator Ttype IFC-1 is designed for calibration of acoustical instruments intended to meter of low-frequency signals according to ISO 7196 :1995 "Acoustics - Frequency weighting characteristic for infrasound measurements". Measuring microphone of the tested instrument is tightly coupled to the acoustic actuator of the infrasound calibrator by a pressure chamber. Internal acoustical actuator produces a low-frequency sound pressure in the cavity.
  • DVM1356 - SOUND LEVEL CALIBRATOR 114dB & 94dB at 1kHz * calibration levels of 94dB and 114dB * output frequency: 1kHz * suitable for microphones with diameter 1", 1/2" and 1/4" * comes with 1/2" and 1/4" microphone adapters
  • Type PF-12 - Infrasound Calibrator Infrasound Calibrator Type PF-12 with a low-frequency pressure chamber is a source of acoustic infrasound wave designed for qualify effectiveness of a half-inch measuring microphones by simoultanous comparing method.

  • 40AC - ½" Free-field microphone Wide-frequency The Type 40AC is a high precision microphone for laboratory work and as a working standard microphone in calibration laboratories. It covers a frequency range from 3.15 Hz to 40 kHz. Its small size and lower sensitivity make it extremely robust and stable. The Type 40AC is capable of measuring sound levels up to 160 dB re. 20µPa.
