Larson Davis SPARTAN 730

The First Truly Wireless Noise Dosimeter

The Spartan Noise Dosimeter Model 730 is designed to make worker noise dose measurements easy and fast. With Spartan, control test setup and measurements directly from the Larson Davis Atlas mobile app. All essential tasks can be completed from your iOS or Android device. LD Atlas allows you to monitor remotely without draining your dosimeter battery, ensuring that you’re getting the valuable data you need the first time. When a test is complete, Spartan communicates with LD Atlas to download the data, which is viewable directly from a phone or tablet. Generate reports, including the full data file, from the mobile interface before sharing via email.
