Find your way through the noise with the Optimus+ GPS sound level meter
We’re proud to announce the launch of the new GPS-enabled Optimus+ sound level meter, designed to make environmental noise monitoring easier and more effective than ever before.
The Optimus+ GPS builds on the incredible technology of Cirrus’ iconic Optimus range, by providing highly accurate location data for every measurement that’s taken. Optimus+ GPS automatically stores location data with each reading, which can be analysed in our licence-free data reporting software, NoiseTools.
There’s no need to purchase a whole new noise measurement instrument to benefit from the GPS functionality, you can simply purchase the module and add it to your existing Optimus+ Red or Green device. It’s also available as a full sound level meter kit.
With optimised battery life, the Optimus+ GPS is perfect for taking environmental noise measurements. The industry-leading time to first fix means that it is easier and faster than ever before to connect the module to a GPS signal.
Find your way through the noise with Optimus+ GPS from Cirrus Research.
