Optimus+ GPS Add-on for Sound Level Meters
Easily geotag all your sound measurements
We’ve designed the Optimus+ GPS add-on for our sound level meters to make logging the locations of your environmental noise measurements easier. Simply connect the module to the base of your Optimus+ Industrial or Environmental to see accurate geo-location data for every measurement you take.
How will the Optimus+ GPS add-on benefit your organisation?
Perfect for environmental noise assessments or outdoor occupational noise surveys, the benefit of precise GPS location data will help you understand noise levels in more detail than ever before. Not only does Optimus+ GPS add-on for Sound Level Meters provide accurate positioning data, but as all our users have come to expect, this instrument comes fully loaded with a host of features and functionality to provide the comprehensive solution to environmental and occupational noise measurement available on the market.
Time to First Fix
Our GPS Module has an industry-leading Time to First Fix (TTFF). NoiseTools automatically downloads GPS AssistNow data to instruments configured to use the GPS Module this helps reduce the TTFF from up to 5 minutes to under 60 seconds.
View all of your data in NoiseTools
As well as being able to see the geotagged data for every measurement on the screen of your Optimus+ GPS enabled sound level meter, you can also view the location data in NoiseTools:
In addition, you can use the View Map button in NoiseTools to view your data on a map or Google Earth image and add these to your assessment reports.
Add on GPS Module that integrates directly with Optimus+ Red and Optimus+ Green sound level meters.
