Microphone IP55 Splashproof

The MI21 microphone is designed to be splash-proof so that it can be used for measurement campaigns in wet or damp weather. A water-repellent seal on the membrane at the sound inlet prevents the electret capsule from being damaged by water.

The IEPE microphones with splash water protection, including MI17SW and RG-50SW, have proven their worth with brake manufacturers, among others, who mount the measurement microphone in the wheel arch in order to record disruptive brake noises.
