MP201 microphone is the best choice for use in IEC61672 Class 1 Sound Level Meters and other noise measurements requiring Class 1 accuracy. The microphone housing and diaphragm are made from the same nickel alloy to ensure the smallest temperature coefficients.
Production quality control for the MP201 uses only 40% of the frequency response tolerances allowed by IEC61672 Class 1 microphones.
