NTi WP40-90 Weather Protection for 1/2'' Microphone M2340 & M2230
The measurement microphones are optimized for a flat, free-field response in the frequency range 5 Hz – 20 kHz. Models for acoustic measurements of up to 155 dB are available.
All microphones are omni-directional and 48V phantom powered. The Sound Level Meter microphones include an electronic data sheet. The Automated Sensor Detection (ASD) of the Analyzer automatically reads this data sheet, and recognizes the microphone model, sensitivity and calibration data. This ensures accurate measurement results.

Outdoor Measurement Microphone
The Outdoor Measurement Microphones offer a weather-protected measurement solution for the Sound Level Meter allowing acquisition of environmental noise data in outdoor applications. The corrosion-free polymer housing, wind screen, waterrepellent membrane and bird spike provide excellent protection from rain, wind, dust and perching birds.
The Outdoor Measurement Microphones M2230-WP and M2340-WP fulfill the Class 1 requirements according to IEC 61672 and ANSI S1.4 for horizontal and vertical sound incidence. For compliance with horizontal sound incidence a spectral correction is employed in the associated Sound Level Meter. The Outdoor Measurement Microphone M4262-WP fulfills the Class 2 requirements accordingly.
