K9000-919 High-Range Microphone Calibrator
Description:
The 9919C High-Range Microphone Comparison Calibrator offers calibration to 20 kHz of both precision condenser microphones and electret array microphones according to IEC 61094-5. By exposing both a microphone under test and reference microphone to a sinusoidal sound field, the sensitivity of the microphone under test is calculated by comparing the outputs in a pressure field. The 9919C Series is available in three configurations: turnkey system, an upgrade to an existing 9155D Model, and as a stand-alone test fixture with reference microphones. With sound pressure levels reaching up to 104 dB, operator hearing is protected by the acoustic isolation chamber.
Benefits / Features:
Frequency Range: 20 Hz - 20 kHz
Expected System Uncertainty – 250 Hz: 0.25 dB
Calibrates both condenser and array microphones
Supports ½” and ¼” microphone form factors
Calibrate with or without removing grid cap
Useful for automotive NVH, flight testing and metrology applications
