Sound Intensity Probe

Intensity ProbeSI512 Sound Intensity Probe is an ICCP powered probe with remote control functions. SI512 can be directly connected to ICCP inputs using two BNC cables. The USB cable between the probe and computer provide the control of sound intensity software.

Features

  • ICCP® powered with BNC connectors
  • Remote-control functions via USB cable
  • Accurate phase matched microphones
  • Face to face configuration
  • 1/3-octave centre frequency ranges: 63 Hz to 5 kHz
  • Well-defined acoustical microphone separation.
