The SpartanTM 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 AtlasTM mobile app. All essential tasks can be completed from your iOSTM or AndroidTM 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.

To begin testing, simply remove the dosimeters from their rugged case and attach them to workers' clothing. After a shift, place the dosimeters back in the case where they will charge and the data can be downloaded. Built-in measurement of motion and bumps, combined with the optional event audio recordings and 1/1 Octave frequency analysis, provide additional data that helps you understand what caused the noise.

The G4 LD Utility software offers another option for control of your testing. With all the functionality of the LD Atlas mobile app, G4 LD Utility adds the ability to complete “what-if” analysis to model potential changes and determine the impact of different data selections.

Spartan Kits offer you options from a single noise dosimeter to a set of ten. Each kit comes in a rugged case, ideal for carrying meters into the field. Once your work is complete, simply pack away your dosimeters and move to the next test site. Kits come in one‐, three‐, five‐, and ten‐meter configurations.
