Larson Davis Spartan 730IS - Intrinsically Safe Sound Dosimeter

The Larson Davis Spartan™ 730IS intrinsically safe sound dosimeter is designed for simple and fast noise exposure measurement in hazardous workplace environments. Using the Larson Davis Atlas™ application, instrument settings and data collection can be controlled with a smartphone or tablet (iOS™ and Android™). The dosimeter should be attached to the worker's clothing at shoulder height for measurements. The LD Atlas™ application allows for setting measurement parameters, performing verification tests, and generating reports from a smartphone, tablet, or laptop. The integrated Bluetooth Low Energy function (BLE) connects the tablet, smartphone, or laptop to nearby measuring instruments, enabling multiple instrument checks and data retrieval. The Larson Davis Atlas™ application is used for evaluating measurement results, creating reports, and sending them 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 separately available G4 LD Utility software offers additional evaluation possibilities, such as "what-if" analysis. The Spartan™ assists in ensuring compliance with various national and international regulations, such as OSHA, ISO, and the EU Directive 2003/10/EC.
