Class 1 Microphone

The outdoor microphone M2230-WP fulfills IEC 61672 Class 1 as well as the ANSI S1.4 Type 1 requirements for vertical sound incidence. For compliance with horizontal sound incidence a spectral correction is employed in the associated XL2 Sound Level Meter.

Effective outdoor protection

The 90 mm wind screen protects the M2230 measurement microphone from rain and dust while reducing wind-induced noise by approximately 15 dB. The seamless design of the water-repellent membrane under the wind screen ensures perfect protection from rain and dust.

Robust design / Easy calibration

The upper section of the weather protection kit is snap-on mounted and can thus be easily removed by hand for convenient and quick calibration of the measurement microphone.
