Measurement microphone Nor1216, Nor1217

outdoor

Nor1216/Nor1217 Outdoor microphone Outdoor microphone for community and aircraft noise Horizontal or vertical reference direction set by external frequency correction Fulfils IEC 60651, IEC 61672 class 1 and ANSI S1.4 type 1 (frequency correction applied) Protection class IP 55 (dust and water) Easy to calibrate with a normal ½ sound calibrator Build in SysCheck verification Microphone verification by SysCheck facility Low self noise typically below 17 dB, A-weighted Delivered with individually calibration certification Build in heating for enhanced weather protection, (Nor1216 only) Directly powered and supported by Nor140 (build in selectable frequency correction networks, heater supply and SysCheck signal generator) The Outdoor Microphone Nor1216 and Nor1217 share the same acoustical and weather protection design for use in all-weather conditions. The Nor1216 is mainly designed for permanent outdoor applications due to the build in heater, whereas the Nor1217 is designed for semi-permanent application where low power consumption normally is important. The Nor1217 uses the standard preamplifier and microphone from the Nor140, making it a very cost effective solution.
