Measurement Microphones

NTi Audio Measurement Microphone
A range of measurement microphones are available to suit your requirements. The measurement microphones combine with the analyzer for a comprehensive sound level meter and acoustic analyzer.

The microphones are 48V phantom powered and include an electronic data sheet. The Automated Sensor Detection (ASD) of the Analyzer automatically reads this data, i.e. the microphone model and calibration data. This promotes faster setup and ensures accurate measurements.

Weather Protection

Microphone Weather Protection
Protect your measurement microphone from rain, wind, dust and perching birds with a professional outdoor weather protection kit. The corrosion-free polymer housing, windscreen, water-repellent membrane and bird spike provide excellent protection from rain, wind, dust and perching birds. A weather protection is dedicated for precise acquisition of environmental noise data in outdoor applications.

There are three types available. The WP30 Weather Protection with two different sizes of windscreens (90 mm and 150 mm) is dedicated for the ½” measurement microphones M2230 and M2340. On the other hand the WP61 Weather Protection is designed for the ¼” measurement microphone M4261. An outdoor measurement microphone consists of a measurement microphone and a weather protection.
