Nor1217 Outdoor microphone
Nor1217 outdoor microphone is a semi-permanent version of the Nor1216.
It features the same weather protection and SysCheck, but is designed for use with the standard preamplifier and microphone supplied with the sound analyser Nor140 , Nor145 and Nor150.
This makes the Nor1217 in combination with the Nor140/Nor145/Nor150 a very cost-effective solution.
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.
