MP215 Microphone
MP215 microphone is a 1/2" prepolarized free-field measurement microphone and the best choice for use in IEC61672 Class 2 Sound Level Meters and other noise measurements requiring Class 2 accuracy.
The microphone diaphragm of MP215 is also made from a nickel alloy using BSWA diaphragm coating technology while the housing is made from stainless steel. The temperature, pressure, and humidity coefficients are better than IEC 61672 Class 2 requirements.
MP215 is an excellent all around Class 2 microphone with proven design for quality, reliability, stability, and performance.
