The Outdoor Measurement Microphones offer a weather-protected measurement solution for the Sound Level Meter allowing acquisition of environmental noise data in outdoor applications. 耐食性に優れたポリマーハウジング、ウィンドスクリーン、撥水ボディ、バードスパイクが、雨、風、塵、鳥から強力に保護します。
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 M4261-WP fulfills the Class 2 requirements accordingly.
The outdoor microphones consist of a measurement microphone and the applicable weather protection:
- M2230-WP: M2230 + WP30-90 / -150 ウェザープロテクション
- M2340-WP: M2340 + WP30-90 / -150 ウェザープロテクション
- M4261-WP: M4261 + WP61 ウェザープロテクション
特長
- Class 1 and Class 2 Outdoor Measurement Microphones for vertical and horizontal sound incidence according IEC 61672 and ANSI S1.4 (with XL2)
- 雨と塵（IP54）、風、鳥から強力に保護
- 腐食に強い材質
- 上部パーツを外し、簡単にマイクロホンの校正が可能

全天候向けの保護機能
The 90 mm or 150 mm wind screen protects the measurement microphone from rain and dust while reducing wind-induced noise. The seamless design of the water-repellent membrane under the wind screen ensures perfect protection from rain and dust.
システムセルフテスト
The Outdoor Measurement Microphone M2340-WP is system self-test (CIC) enabled. Automated self-tests may be performed by NoiseScout, the unattended noise monitoring solution, in combination with the Sound Level Meter. This ensures reliable operation and precise measurements.
頑丈な設計と容易な音響校正
全天候型プロテクションキット上部はスナップ式の取り付け構造を採用、手で簡単に取り外しできるため、測定用マイクロホンを素早く音響校正できます。
