Microphone IEC 61672 Class 1

MP201 is 1/2" prepolarized freefield measurement microphone. It is ideal microphone to be used in IEC61672 Class 1 Sound Level Meters and other noise measurements where the Class 1 accuracy is required.
MP201 microphone diaphragm is made from nickel using BSWA diaphragm coating technology. The microphone housing is made from nickel alloy to ensure the smallest temperature, pressure, and humidity coefficients.
MP201 uses 40% of the frequency response tolerances allowed by IEC61672 Class 1 in production quality control. Each MP201 microphone is supplied with its individual calibration for frequency response and sensitivity.
