MI17SW Splash Proof IP55
The MI17SW microphone is designed with splash water protection so that it can be used for measurement campaigns in wet or humid weather.
A water-repellent sealing of the membrane at the sound inlet, prevents the damage of the electret capsule by water.
The IEPE microphones with splash water protection, also MI21 and RG-50SW, have proven themselves, among others, at brake manufacturers, who mount the microphone in the wheel housing to record disturbing brake noises.
