Larson Davis Spartan 730IS - explosion-proof noise dosimeter

The Larson Davis Spartan™ 730IS explosion-proof noise dosimeter is used for simple and fast measurement of noise exposure in hazardous workplaces. The Larson Davis Atlas™ application allows for instrument settings and data collection control using a smartphone or tablet (iOS™ and Android™). The dosimeter should be attached to the worker's clothing at shoulder height for measurement. The LD Atlas™ application enables 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, allowing for 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™ helps ensure compliance with various national and international regulations, such as OSHA, ISO, and EU Directive 2003/10/EC.
