Outdoor Noise Monitoring System
The next generation in remote noise measurement instruments.
The Cirrus Invictus outdoor noise monitoring system is a purpose designed environmental noise measurement instrument designed for use in a wide range of applications from short term noise measurements to long term noise monitoring projects.
The Cirrus Invictus outdoor noise monitoring system can be used on its own as a portable environmental noise monitor or can be combined with other instruments and sensors to form part of a larger, more comprehensive noise measurement and management system. For medium and long term noise monitoring applications, the Invictus can be combined with a secure enclosure for wall or mast mounting.
Ease of use is key to the Invictus and the large, clear colour touch screen allows the instrument to be deployed quickly whilst allowing the user to see the exact status of the system.
Using the very latest technology, an Invictus is simple to set up and deploy whilst providing a wide range of noise measurement parameters. Supplied with the Noise-Hub2 software package, the Cirrus Invictus outdoor noise monitoring system is the ideal noise measurement and monitoring instrument for any application where ease of use and high performance are essential.
The advanced features of the Cirrus Invictus outdoor noise monitoring system are available on all versions, allowing any noise monitoring application to be covered.
Using the very latest technology, the Cirrus Invictus outdoor noise monitoring system is simple to set up and deploy whilst providing a full and comprehensive range of noise measurement parameters.
- Live audio playback via the Noise-Hub2 software
- Colour touch screen interface simplifies set up and deployment
- Simultaneous measurement of all parameters
- Full weather protection with dual-skinned windshield
