Weatherproof microphone unit

MR40 with microphone stand - option

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.

  • Reference direction of sound incidence 90° to the microphone axis
  • Sensitivity 50mV/Pa
  • IEPE supply 2-20mA BNC
  • Frequency Response: 3.5Hz – 20kHz
  • 3.5Hz-4KHz: ±0.5dB
  • 4KHz – 20KHz: ±1.5dB
  • Class 1 WS2F – DIN IEC 61094-4 
  • Acoustic noise floor 18 dB(A) 
  • Measurement range to SPL Peak (5% Dist.) 146 dB
  • Temperature range -20 to +60 °C

1/2" measurement microphone rain cover

In principle, all 1/2″ measurement microphones can be converted with these parts.

11.7mm-60 UNS protective grid thread is a prerequisite for converting a measurement microphone into a weatherproof microphone
