Larson Davis Spartan 730 Noise Dosimeter

The Larson Davis Spartan™ 730 noise dosimeter is used for simple and fast measurement of noise exposure in workplaces. Using the Larson Davis Atlas™ application, instrument settings and data collection can be controlled with a smartphone or tablet (iOS™ and Android™).

For measurements, the dosimeter should be attached to the employee's clothing at shoulder height. With the LD Atlas™ application, measurement parameters can be set from a smartphone, tablet, or laptop, verification tests can be performed, and reports can be generated. The integrated Bluetooth Low Energy (BLE) function connects the tablet, smartphone, or laptop to nearby measuring instruments, allowing for multiple instrument checks and data retrieval. The Larson Davis Atlas™ application is used for evaluating measurement results and generating reports, which can be forwarded via email. In addition to noise events, vibrations and movements can also be recorded. The measurement task can be expanded with sound recording and octave filter options. The G4 LD Utility software can be separately acquired, offering additional analysis possibilities in evaluation, such as "what-if" analysis. The Spartan™ helps ensure compliance with various national and international regulations, such as OSHA, ISO, and the 2003/10/EC EU directive. Typical Applications
