Norsonic NOR1217 Outdoor Microphones

Explore the Norsonic NOR1217 Outdoor Microphones — engineered for precise, standards-compliant acoustic measurements. Features Outdoor microphone for community and aircraft noise. Fulfils IEC 60651, IEC 61672 class 1 and ANSI S1.4 type 1 (when used with Nor140, Nor145 and Nor150 sound level meters). Protection class IP 55 (dust and water). Easy to calibrate with a normal ½” sound calibrator. Microphone verification by SysCheck facility. Low self-noise – typically below 17 dB, A-weighted. Directly powered and supported by Nor140 and Nor150 (built in selectable frequency correction networks and SysCheck signal generator). Low cost. Use microphone and preamplifier supplied with Nor140, Nor145 and Nor150. Approved by PTB, Germany.
