Outdoor microphones

Outdoor microphones

Unprotected measurement microphones are sensitive to environmental factors such as wind, rain and snow. This shortcoming has been eliminated by specially designed units that protect the microphone. G.R.A.S. offers two types; Outdoor microphones for permanent outdoor use that can withstand all weather year after year and Environmental microphones designed for outdoor use in a very long period i.e. a year og longer.

Both types are available in two versions:

0° incidence for airport noise monitoring and 90° incidence for community and traffic noise monitoring.

All G.R.A.S. versions comply with the relevant international standards for monitoring noise.
