A semi-permanent version of the Nor1216 is the Nor1217 which features the same weather protection and SysCheck, but is designed for use with the standard preamplifier and microphone supplied with the Sound Analyser Nor140 and Nor150, making the Nor1217 in combination with the Nor140/Nor150 a very cost-effective solution.
