NOR-1212 Outdoor Microphone Protection Kit
GRAS-41CN Outdoor Microphone
An outdoor microphone unit for permanent outdoor installations, for example in systems for monitoring community or traffic noise. The unit has a built-in A-weighting network, a ± 20 dB amplifier, and an electrostatic actuator for a complete check of system functionality. This unit is type approved by PTB as part of a monitoring system for type 1 Sound Level Measurements.
This unit is fitted with a special ½" microphone for measurements at 90º incidence. This microphone (the Type 40AS) is optimised for use with its windscreen and rain protection. Type AM available for Airport monitoring
GRAS-41AL Outdoor Microphone
Outdoor Microphone type 41AL is designed for semi permanant outdoor measurements covering periods from a few days to several weeks. They can withstand continuous rain and operate over a wide temperature range. Calibration requires adaptor GRAS RA0010. Optional Desiccant unit type GRAS-AL001 recommended
