Our primary level microphone calibration system for calibration of laboratory standard microphones.
Type 9699
A primary level microphone calibration system for calibration of laboratory standard microphones.
Type 9699 applies the pressure reciprocity calibration technique and calibrates to the highest possible accuracy. A free-field system is available as Type 9799. The system performs pressure reciprocity calibration according to the method described in IEC 61094-2 for determining the pressure sensitivity of microphones described in IEC 61094-1 (Laboratory Standard Microphones).
The system is intended for National Metrology Institutes and other high-level laboratories. It is a turnkey system for routine measurements, which can be set up to meet the requirements of the user.
The system can work in a ‘normal’ laboratory environment with no specific precautions with respect to background noise and vibration.
