OM225 outdoor microphones have been specially designed to achieve the free-field frequency response both in 0° and 90° direction of incidence within the limits of Class 2. It’s suitable for aircraft, airport, urban, traffic and industrial noise measurement. Each microphone is supplied with an individual calibration certificate that contains the actual sensitivity and free-field frequency response data for the complete set of outdoor microphones. Users can use the calibration data to correct the measurement data for more accurate results.

OM225 meets the IP54 ingress protection rating. The 90mm windscreen, internal rain hood and dust mesh can fully protect microphone to against wind, rain, snow, dust and other severe weathers. The bird spike prevents impact of perching birds to the measurement.
