The 19SW microphone has been designed to be resistant to splash water.
The microphone is therefore suitable for use in measurement campaigns under wet and damp weather conditions.
An IP55 water-repellent seal on the membrane at the sound inlet prevents potential damage to the electret capsule caused by water.
The IEPE microphone is suitable for use in standard industrial environments and for all noise measurements with a sound pressure level of up to 130 dB.
Calibration is possible with a commercially available microphone calibrator and a 1/2″ to 1/4″ adapter.
The MI19 microphones are equipped with a BNC socket so that standard BNC cables can be used.
A TNC plug version is also available on request.
