Weatherproof microphone unit
MR40

Outdoor microphones are used for outdoor acoustic measurements or monitoring of tissue and traffic noise.
ROGA outdoor microphones are equipped with a windscreen, a rain cover and a bird deflector to protect them from such and other weather influences.
The MR40 outdoor microphone can be calibrated with a sound calibrator eg CA111 by carefully removing the windscreen and rainscreen.
The sound entrance at a 90º angle to the microphone axis is ideal for monitoring ambient and traffic noise.
MR40 is a 1/2-inch pre-polarized condenser outdoor microphone.
It is suitable for continuous use in rainy days or in a very high or very low temperature environment.
MR40 uses a WS2F and IEC 61672 Class 1 MP40 measurement microphone, which is characterized by its stability.
It is the best choice for long-term outdoor use, such as noise monitoring.
